    Having just come off tour with last show in San Antonio on St. Patty's Day, I can attest that the laserist (yours truly) was the ONLY one not celebrating

    Are you sure? Not direct laser diode I'm afraid. Just microchip or so with IR source and some nonlinear.
    What is your info source?
    Thanks

    Its a NECSEL array, another "good luck cleaning the beam up to fit on the scanners" source... Its been out for two years.
    Ushio owns NECSEL, so I can guess what their quantity one price is. Basically a ton of microcavity surface emitting lasers with a doubler crystal bonded on top. Two rows of 24 emitters per row, or an optional 400 um fiber for output. That QCW on the data sheet means, Quasi CW....

    Had to look this up: https://www.ushio.com/product/necsel-yellow-577-laser/
    20a!
    Looks expensive.
    Looking for yellow for lumia, but I don’t think this is the droid I’m looking for.

    Is that some kind of IR tapered laser emiters (Bragg reflector+tapered amp) emitting 1154 + PPLN (SHG)?
    Or maybe IR pump + YLF/YAG+ RAMAN SHIFT + SHG (PPLN)?

    What do you think?
    Thanks
