death rays, for example - have proved to be overblown. Their peaceful application, on the other hand, can be seen everywhere from cutting and welding

It's all in the application. Take those lasers that are used for cutting and welding and point them at someone, and bam, you have a death ray.

QCLs are us. Really useful functional ones are at least a decade away. They have seen lasing but 1959 had the MASER followed shortly by the LASER. but commericially viable and useful ones weren’t available even for OEM use until the 80s

Merely of interest. :')

Nothing can defeat the Quad Laser.

[FreeKeys]

This creates yet more excitons which produce more resonant light waves and so on, until energy begins to cycle between light and matter so fast - in just a few trillionths of a second - that according to the rules of quantum physics it becomes impossible to tell in which of the two states it is stored.

If it doesn't light, does it matter?

(Sorry. Couldn't help it.)
