Electron lasers???? This much be something very new, I never heard before and I am unable to imagine what it can be.

He didn't say electron lasers. He said free-electron lasers. And remember I said there's this thing called Google? Perhaps you find it hard to use. Here I'll help you.

http://en.wikipedia.org/wiki/Free-electron_laser - FELs use a relativistic electron beam as the lasing medium which moves freely through a magnetic structure, hence the term free electron.

http://www.lightsources.org/cms/?pid=1001328 - Free Electron Lasers (FELs) represent an increasingly important kind of light source with a brightness that can be up to one billion times higher than that of ordinary synchrotron light. FEL’s differ from conventional lasers in that they use the electron beam as the lasing medium rather than a gas or a solid.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
