Not toxic, off topic, but a thing of beauty; the Novus Varia RYG surgical laser. My favorite laser, found on ebay, I marked up the photo to show what is going on.
Rated max. pulsed output power:
G: 532 @ 1.5 W
Y: 561 @ 600 mw
R: 659 @ 600 mw
I have three of these babies, planning on converting the 532 and 659 sections of one unit to OC only 1064 and 1319 nm to SFG 589 nm yellow Of course, pushing the power harder.
