Excuse my idiocy!
I'm just wondering why 980nm isn't easily frequency doubled into 490nm like 1064nm is into 532nm. Is there not a proper crystal to do it?
You can do it, but you don't see them around because its not producing any wavelength that anybody wants. Plus as I understand it you need to perform some diode correction.
It's actually not as bad as you'd think. I can probably get a functional module for ~500-700 bucks.
For not a whole lot more than that, you can get a 490nm single mode diode.
uh...where? Unless you are referring to the 488 diodes, which are several thousand $, not several hundred.
I think I won't ever touch a 488nm diode!
Well at least if I do, I won't use a drill press on it.Give it 5 years, you might not be saying that^ then.

I am.
And they're not "several thousand", they're a little bit over one thousand.
And that's "not a whole lot more" than $700.
