How Accurate is the Tech Speak about the Laser?


I'm wondering how accurate Chris's explanation of the laser solution is -- in other words, is it actually possible to build such a laser, would it work as seen in the flick, is it all just sci-fi technobabble, etc?

I transcribed the scene, without Kent's interruption, as follows:

It is possible to synthesize excited bromide in an argon matrix. Yes. It's an excimer, frozen in its excited state. It's a chemical laser, but in solid, not gaseous form. Put simply, in deference to you, Kent, it's like lasing a stick of dynamite.

As soon as we apply a field, we couple to a state, that is radiatively coupled to the ground state.

I figure we can extract at least ten to the twenty-first photons per cubic centimeter, which will give one kilojoule per centimeter at six hundred nanometers, or one megajoule per litre.

You will have to get more info from a laser expert....BUT I do NOT think much of it is real 'laser tech". The part about a chemical laser IS real--but the way they DID it and TALKED about it--likely as real as the 'flux capacitor".

A frozen chemical laser medium? do NOT know if that is possible or not an Iodine laser--it IS possible I think...but NOT as depicted in this movie.

It's all bull$hit. I tried it the other day and it didn't work.

Huh, you should have reduced your bromide to 20ml. Mine worked fine.

I can tell you one thing -- the output of the laser is purplish, yet the 600nm wavelength is too long for that.

Duh. It was made visible in post for the movie audience!

I found this in Wikipedia. "The solid xenon-halogen laser proposed and built by Chris in the latter half of the film, though in the realm of science fiction, was based on theory of the time. Real Genius, through consultant Martin A. Gundersen (who played the math professor), was later cited in an academic publication which detailed the scientific basis behind the laser."

The idea presented has a foot in actual science but I really don't know if anyone followed through and to what lengths.

Martin Gundersen is still at the University of Southern California today.
