    Thanks for your time in the detailed explanation. It's not trivial to get a grasp on the overall situation when coming from academia int the 'real world'!

    ... halving 1064nm will give 532nm, what's green, not blue! - what's the process and source to get high power blue by halving frequency?

    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    ... 946nm diodes? - what output energy and beam specs?

    I have 975nm diodes with up to 30Watts out of a 0,1mm-fiber and there are stronger modules with up to 150 Watts out of 0,2mm-fibers - but didn't hear of someone using them ...

    What do they pump 589 with?

    They do SFG with both 1064 and 1319nm with a periodically poled KtiOPO4 or Zn:LinbO3 etc crystal

    Yes, this is ND:YAG on the 946nm low gain transition + SHG

    That explains the low conversion yield. I just got a 470nm 25mw diode!! Afraid to power it up. Engineering sample it seems.

    Want... Jordan had some higher wavelength blue sm diodes for a very brief time. Unfortunately I missed out on them. I keep hoping that 470nm+ sm diodes finally make it to our hands.

    I got one of those from Lazerman and incorporated it into a graphics / glow in the dark projector. The 470-473nm gives you light blue without leaving a trail on glow in the dark paint, which is darn cool. My diode seemed to peak out at around 100mw, but I set it at 80mw in the projector. These things are rarer than the great white bat, so I hope it holds out for a long time at that power.
