Love that movie, sadly the first thing I thought of.

I imagine plasma mirrors are much harder to aim in zig-zag patterns across campus to your beautician water-slide party.

Look, there's a more pressing issue here. It is Plasma GUN, not plasma MIRROR! Okay? What the hell else does plasma do except activate with the 7 key and kill cyber demons?

As a laser engineer...no one is worried about this. Generally, You don't get heating effects at time intervals measured in femto seconds.

Additionally, No one is talking about lasers in the Exawatt range. Petawatt lasers are bleeding edge.

The big news will be fiber lasers going into the tens of kilowatts. This could be all sorts of game changing in lots of areas...military, mining, tattoo removal

Funny,

That movie was a huge inspiration in my life. It pushed my interest in technology and lasers. After a while I got my double E degree and started playing with some cool shiate.

I also find it amazing how many people love that movie. I always thought it was kind of obscure until I was farked.

God, that's hot. No pun intended.

Hmmm... want to have a short-wavelength mirror and a movie quote as well?

Professor Hathaway: I noticed you've stopped stuttering.

Bodie: I've been giving myself shock treatments.

Professor Hathaway: Up the voltage. ...

Pfft. Everyone knows that masers are where it's at.

Can these plasma mirrors be turned into a phased rifle somewhere in 40 watt range?

/or is it just what I see in the article?

b2theory: As a laser engineer..

are you gettng a kick out of these replies?

I was telling them this years ago.... nobody listens

ICE IS NICE!!

from TFA - plasmas are gases, which means they move around and have density fluctuations and other nasty properties.

not all plasmas are "gases".... the Quark Gluon Plasma is a (nearly perfect) liquid.

whether a plasma is a 'solid', 'liquid', or 'gas' plasma depends on the strength of the interactions, just like for non-plasma phases of matter... cheers

Ya need acetone to clean up Quark Gluon Plasma.

Hey B2theory, I'm a laser engineer too. In fact, now I manage a laser development group here in the Phoenix area. Drop me an email and lets swap some info.
