Ok we know that all blasters fire plasma bolts. And we can identify lazer weapons like the DS super lazer and the ones on the landing craft in ep2. But are light saber blades lazers or plasma? Ive seen lazers and plasma bolts and you can see that lazers are a solid color with no white center and plasma bolts have a white center with the color around it. They basically can do the same type of damage burning with great intensity. Lightsabaers have a white center so I belive they may be plasma not lazer. Be open minded and thinik about it before you post! Think about plasma not plasma bolts and think about lazers by themselves. In ep1 when Quigon sticks the blade into the blast door he melts it cause the beam does not leave the door so it always gets hotter. Plasma bolts just impact and disapear, no continuing contact. If plasma stays in one spot without moving...you get the idea. A solid beam of plasma will cut like a lazer no? It wont just impact and splash. What do ya think? Lazer or plasma?:dsaber::saberr::saberg::saberb:

A light beam...wtf is that. You mean a lazer? You wanna elaborate on that? A very hot light beam. Blasters dont shoot lazers if they did the shot would move a the speed of light. Which it doesnt. Blaster bolts move at the speed of bullets. Did you really read my post?:rolleyes:

And Ani in ep 1 called it a lazer sword cause he didnt know what it was really called. Hes a little kid and he called it what he thought it looked like. I little kid.

Blasters don't shoot plasma bolts, they shoot blaster bolts. And Lightsabers are sabers of light. not sabers of plasma. They're lasers.

I think the Dark Side has clouded your vision, my friends...

A lightsaber focuses pure energy, from a rather large power cell (or several small ones, as seen in Qui-Gon Jinn's lightsaber design) through a special "ilum" crystal from the planet Ilum. Each new Padawan learner must travel to this planet to recieve their own ilum crystal... but anyway: pure energy, focused through a crystal to give the energy form, usually in the form of a long blade, but it can be adjusted. A lightsaber blade is focused pure energy, which is why it can cut through everything apart from another pure energy blade. Plasma is a totally different thing which requires a chemical reaction to take place in the ammunition store before firing, and laser is refined light energy (not pure energy like a lightsaber) which also relies on things like kenetic energy and thermal energy to be fired (which is why a laser gun will overheat if used too frequently). A lightsaber blade is pure, untouched energy which can be focused only by the special ilum crystals. Ilum crystals are never found in blasters...

The name 'lasersword' can make this mistake easy, but this name was only used in early "Star Wars" stories when the lightsaber technology was not fully understood by writers!

Anikin in episode 1 says to qui gon...

*you are a jedi arent you...
qui gon: what makes you think that?
*i saw your LASERSWRD!


i think thats the words...

Lucas uses the phrases "laser swords" and "lightsabers" interchangably in his scripts. Just one example from the Episode I script:
...QUI-GON and OBI-WAN leap to a standing position with their laser swords drawn. TC-14 jumps back, startled, spilling the drinks on its tray...
Actually, now that I'm looking through the script, it seems Lucas uses "laser swords" more often of the two in describing the scenes.

You want to elaborate on what "blaster bolts" and "pure energy" is? Its evident that people did not really read my first post. THINK about it and if the people at SW say it is this or that find out what that means. So if in the end all they say is that blasters fire "blaster bolts" and lightsabers are "pure energy" and say nothing more about it then its open to fan speculation cause they dont bother to make scientific sense out of their stuff. Ok?:rolleyes:

Well... Lucas says "laser swords", indicating that lightsaber blades are indeed lasers... so I'd say that's basically the final word on that part of the debate ;)

And hey, I'm big on fan speculation; I'm notorious for that, myself, especially since I've thrown out most of the EU references. And in this debate, in this forum, I'd encourage everyone to stay far away from the EU. However, my point above is that what Lucas says goes. They've been laser swords at least since the second draft of Star Wars, and they're still laser swords a good 25 years later. Laser swords are part of SW canon by Lucas' continued allusions to them in his scripts.

If you are picking quotes from the 'Episode I' novel, then George Lucas did not say "laserswords" because he didn't write the novel! Also, the Illustrated Screenplay of 'Episode I' used "laserswords", but this was not written by Lucas either! The original storyline, written by Lucas, is never seen, because it is tweaked, modified and (some parts) re-written by other people.

Laser: uses raw energy as a source of power, but final blast affected by kinetic, heat and sound energy, plus several different catalysts.

Plasma: chemically created form of energy which relies on several chemical reactions to charge up a blast.

Pure Energy: un-disrupted, un-altered form of energy which only touches a special crystal before being emitted. The rawest source of power, plus the most deadly.

Three distinctly different types of energy, used to power three distinctly different weapons. A lightsaber uses a special power source which cannot be compared with conventional blaster weapons, thus meaning that a lightsaber uses niether laser or plasma to create that glowing blade.

PS: Lasers don't hum or crackle, whereas pure energy does, hence the lightsaber sound. In all television, radio and media interviews, George Lucas has always used the words "Jedi lightsaber".

Sorry im not sure whether you were talking about the ''Lucas physics'' behind the weapons or a possible reallife equaviliant.
ill post ne way:

Star Wars is indeed the only place in the galaxy not to mention reality were you will find LASER swords. im not sure if any of you realise ( not ment to sound offensive) a laser has very similar properties to light meaning that unless u use a black hole or gravity well, it will not stop conviently at the end of a point (e.g. like a flashlight).

Count Tyranus was correct in saying it was not a Laser. However, plasma ~(unless your referring to blood plasma) is not a chemical, And can be produced and even contained in electromagnetic fields. Just to keep you thinking, There are already prototype tests of REAL lightsabres without some huge power source.

Thanks you very much Tyranus. I think this is our answer. Very well explained and it makes sense and its canon. And Jedimonk EU says nothing different about lightsabers or any weapons in general that differs from what canon says. I think before you decide to bash something you should learn more about it. Unless you HAVE read EU and just forgot. You still dont have to like it just dont bash it on baseless stuff like weapons. And covenant what you said about plasma being able to be contained electromagnetically that is very good info but in SW its pure raw energy. I dont know what pure energy IS exactly so maybe someone who know alot about science can explain.

Actually, George Lucas, when you turn on the audio documentary for episode 1, refers to lightsabers as their laser-swords. So they are laser swords.

Thank you, ET Warrior (and I'm gonna assume you mean "episode I")! Lucas does say "Laser Swords"... and he did write the Episode I script. He had a co-writer on SW2, but he was the one who wrote the script for SW1.

obviously lightsaber blades are a unique substance made by the fictional "ilum" crystal when some form of light or energy is passed thru it. its not a laser, its just 'laser' is the closest word in the english language that would describe such a substance, it's an acceptable descriptive term.

If I wasn't absolutely diabolicaly dangerously over-the-top in mad crazy love with everything to do with "Star Wars", then I would say that you can all type a very convincing argument. However, what I did say was true (not wanting to sound big-headed, but I probably am). Thanks for letting my brain unleash all this stored-up information somehow, DarkJediNut.

P.S: I did some checking, covenant_bad, and plasma is NOT a chemical, as I said. You were right, and I was wrong. Ah well...

Well, I'm not a rocket scientist, (I'm actually only 13:p ) but I happen to know quite a bit about plasma. I know enough to know that the best way we currently have to build real lightsabers is plasma. All you need is to create an eletro-magnetic field to contain plasma which is fired out at an angle so that it loops and does a sort of figure 8. This would of course be so tight that you wouldn't notice that it's not just one bar of plasma. It wouldn't really be that hard. I read on a news site (I think msnbc) that their working on that design. That's where I heard the above. Now, someone claims to have made a real one and here's the address to that web site. Complete, of course, with a forum. http://geocities.com/Lasersword2001/Lightsabre/LightsabreConstruction.html

Awsome site, check it out! the construction manuel and frequently asked questions sections are currently down. geocities :rolleyes: Check it out!

I believe Tyranus is still correct. The popular description of a lightsaber is lazer sword because that is what it looks like. Its how best to describe its look. George said lazer sword because he was trying to make sense to the general puplic that doesnt know much about SW or he was thinking back to when he first was making SW and called it what it was called when SW was still in concept or he likes calling it what it looks like for fun cause he likes to say lazer. Lazer! Whoa cool word Ill say it again LAZER!:) Anakin in ep1 called it lazer sword cause thats what he thought it was. He didnt know it was called a lightsaber and he didnt know it wasnt a lazer. He was little kid and little kids always call what they see what they think they look like. In fact EVERYBODY does. A lightsaber looks like a sword made of lazer. But its not cause the official encyclopedia or whatever Tyranus refered to said it was pure energy. An unaltered undisrupted form of energy not a lazer. Have you seen lazers in real life? I have and they do NOT look like lightsaber blades. In the movies they dont look light lightsaber blades. Look at the DS superlazer look at the turret lazers on the dropships in ep2. Lightsabers are not lazers.:duel: :lsduel:

Btw nice sig Jedi_Monk;)

I used to be really into this, so frankly, I know quite a bit about it. I can tell you this much, if lightsabers in the star wars universe are not plasma, I don't know what they are because they sure as heck aren't lasers. And, wrong again darkjedinut, yes that's true. you can see industrial strength lasers, but you were wrong about not seeing laser pointers. Look at "green laser pointers" on ebay. They're about $100 but you can see the beam. The reason lasers aren't going to be lightsabers is because the blade of a lightsaber is very thick. Especially in episode II. What you can see on those lasers is pencil lead thing. I'd have included a picture of the green laser pointers beam in the post, but I deleted it off my computer, and I can't seem to find the site. Just look on ebay. Kinda lengthy post eh?

Hold on a sec, Are we talking about "real" lightsabers? Or lightsabers in the star wars univers?

If it's the star wars univers, then the answer is pure energy.

If it's real life, then the answer is plasma.

It's as simple as that.

In my view Lightsabers are Pure Energy (because it sounds cool)

Blasters Fire Plasma Bolts. Why? Because,

1. You can see the bolts moving, and I dont _think_ that would happen if it was light beam <it would be moving as fast as light of course>
2. People recoil from blaster bolt shots, and they would not if it was a light beam, <it should just melt their armour or whatever, according to a book I read>
3. You can see the bolts in space. <it would be impossible if it was some kind of laser, because lasers require dust to be seen, as mentioned earlier>
4. Finally, it is said that blasters are usually powered by packs filled with Tibanna Gas <and plasma is just a gas which has lost all of it's electrons>

For example in Issue 38 of the Official Star Wars Factfile it says in the Clone Trooper Equipment section........

"Though clone troopers specialized in their battlefield roles, they all recieved training in the two basic DC blaster weapons - the blaster and the blaster rifle. These fired charged plasma bolts. The inherent instability of those blue bolts made aiming difficult, even for the highly trained clone troopers. "

However, somewhat confusingly it goes on to say......

"Sheer weight of numbers made up for this, and the plasma bolts packed a bigger punch than standard blaster bolts."

But the Essential Guide to Weapons and Technology says that 'all modern blasters follow this configuration' - meaning the 'excited gas' configuration. The Star Wars Visual Dictionary would probably also agree, if I could find it......

Oh, and I dont think lightsabers could be laser, because lasers don't just stop after 3 feet.

True, Star Wars is held "A long time ago in a galaxy far far away..." The laws of physics may be different over there/back then, especially if they were even in another universe.
Then again it may just be that their technology is so advanced that we have no idea how lightsabers are made/work.

Also, another reason why lightsabers made from lasers on earth would not work,
the blades would pass through each other, which would make for interesting fights!

It's like the seismic charges in AotC. There is no way that you can have a seismic charge in space, there is nothing to carry the sound waves. Yet it exists. Much of Star Wars Physics is impossible.

Okay, now apart from these other questions...

Do lightsabers give off heat? Light? And do they carry mass in the sense of "boffing" things like a bat or do they strictly cut?

I saw a massive thread topic about this all explaning all points, very similar to this - shame I can't remember :(

Purple_Tentacle
09-30-2002, 09:19 AM
well i dont know if u want people with EU experience to answer that, but my personal observations from the movies is that :

Do lightsabers give off heat?

I'd say any heat given off could be felt close to the blade but most of the "energy" including heat energy would be contained within the blade itself, hella compact. i'd say that the blade might heat the air around it, but not give off much heat itself.

Light? YES absolutly.

And do they carry mass in the sense of "boffing" things like a bat or do they strictly cut?

I'm thinking that they strictly cut, but when you see Qui-gon put his blade into the control room door you get the sence that the denser the material to be cut the harder it'd be to cut thru it. so maybe they do have mass.
