l, too, have a new toy, but considerably more practical.

You are looking at an industrial laser,which emits an extraordinary light, unknown in nature.

It can project a spot on the moon. Or at closer range, cut through solid metal. I will show you.

great video, but i was a bit upset that he didn`t use a `cat toy` at the start when he was explaining the uses of lasers. my cat loves it.

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 cubic centimeter at 600 nanometers, or, one megajoule per liter.
