ruby laser
« on: December 06, 2005, 11:48:30 PM »
I have a homework question that I've been working on.
I know that in a ruby laser, the flash tube excites the electrons in the ruby that is composed of Al2O3 and some Cr.  Using one fully reflective mirror and one partially, it shoots out photons in one direction.  What properties exactly of ruby makes it such a good material to use in lasers?

they're fairly clear yet vividly coloured, and they're resistant to heat.

The properties that make ruby work as a laser lie in the electron energy levels in the crystal.  

Try htpp://www.wikipedia.com and look for "laser" and "stimulated emission"
