Real-Life Laser Technology

I was just on YouTube, and I saw these awesome videos.

Laser Flashlight Hack!
Blu-Ray Phaser
New 007 Laser Weapon - Revealed!

And here is a light-saber video:
Lightsaber

Nah, light saber will never be truth becauce you can't project a laser beam that would end up like a sword...

 

[The Reborn Devil]

Ye, if we would ever make a lightsaber it would be ridiculously long.

 

[-Berz-]

Why not? Think of magnetism or something, lets say that laser "particles" are metallic and that you put a magnet in a handle?

Think in this way. Oh and nothing is impossible

 

[NhazUl]

it would be a very, very strange world if photons possessed such properties.

 

[TheDivineBoss]

Projectile weapons first.
Railguns second.
Thén lasers.

 

[noob134]

US already has lasers.

 

[Tleno]

Those just heat up the missle warhead so it would explode.

 

[-Berz-]

Well laser is just a ray of of some energy.

Have you seen a water cutting steel or any other material? Water mixed with particles of sand charged trough a really, really small hole under great pressure, I'm not sure but I thing it can even cut glass(glass is "impossible" to cut, because glass is braking(lets say you need some specific dimension) you have to brake it(of course you have tools that looks like saws or something, but those tools brake the glass)
Also known heat laser accurate 90degrees cutting down to 15 mm, simple beam of heat, can also cut trough everything.

Nothing is Impossible for Kim Possible

Oh and nothing is impossible

That's a common misconception.

 

[-Berz-]

That's a common misconception.

Actually I put that in because I was wondering if anyone would notice, hehe.

Well I can tell you that photons which are light "particles" (actually they are not particles but quantum particle (not sure about the english word))
are NOT magnetic. And as they are moving with lightspeed I don't think there is a way to stop them.

Only thing I was thinking of could be something like this:

[The Reborn Devil]

It is actually possible to slow down light. Really tricky though, and your lightsaber wouldn't be really mobile, making it a stationary lightsaber... Not very useful.

 

[Kwanz4]

They actually have made a light-saber in real life--but it is not like a sword. It also was so hot that it could kill anyone who got within 15 feet of it.
