Pretty sure it is a crystal that has an infrared diode pumping through it. So yes it has a diode, but that isn't what produces the 532nm wavelength
Ah, okay, thanks guys. Tried to look it up but it was a bit confusing. I knew 532 lasers were more expensive but didn’t know the exact reasoning. I’ve always been a green guy so I always wanted a nice 532, but those high powered ones are crazy expensive.
520nm isn’t bad but I definitely prefer the color of the 532nm.
This is remarkable. Are there readily affordable sources for the 488s now? Checked DTRs site and it doesn't look like he has them.
Wow, reps are astronomically huge these days.
