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 it 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 cubic centimeter at 600 nanometers, or, one megajoule per liter."
We use it in welding. Helium/Argon mix makes a world of difference compared to straight Argon. Aluminum has an oxidation layer that the helium cuts through. Can get a much cleaner weld using Helium/Argon than opposed to straight Argon.
