Am I Blue? Lines other then 472 in Doubled / SFM Yag in the Blue Spectrum

[LSRFAQ]

I found the attached paper on the web... By accident .


So ~ 469 and 471 are also available with enough pump power, tuning, and the right doubling crystal, plus an intracavity etalon for tuning. If you have a spectrometer with enough resolution, you may see faint traces of these lines in a 472 Blue YAG....

Interesting. The math checks out, I never knew these were actually made/researched but they are in my theoretical chart for YAG

Nice Chart, wait till you do Vanadate, it will be a major headache with all the extra Raman shifted lines.

Nice Chart, wait till you do Vanadate, it will be a major headache with all the extra Raman shifted lines. I've had 543.7 lase as a secondary line in a 1 Watt CW 532 system, so you can add that to your verification list.

Here is a bit of fun for you...
