    Default Dye Laser pumped with DPSS...

    I scored a Laserscope model 630 dye laser on ebay for cheap, I am wondering if it is possible to use 5-10W of CW green to pump it and get a couple watts of red out? Does the Q-Switching make a big difference?

    You have apples and oranges.

    CW DYE means you need to flow the dye past the pump focal spot in about 200 nanoseconds to prevent triplet state quenching. This is why CW dye lasers come with narrow , almost 100 psi, jets. Pump threshold is several watts, and the more, the merrier..

    Pulsed dye doesn't worry about triplet states because the pump is brighter and very short. its slow flow..
    That is why a slow flow dye cell works, 7 nanoseconds of doubled yag or 3 nanoseconds of N2 @ 332 does not have time to drive the dye to the triplet state. In fact, the shorter the better... And average power threshold is much lower, but the peak per pulse is huge. This is why you see air in a lame nitrogen laser pumping dye on youtube, but it doesn't run cw at 5 mW of pump. But that N2 has kilowatt peak power per pump. It works with big, huge, dye cells, making construction much simpler..

    Sorry Ben, but you need Qswitched or Ultrafast light to drive that one.. You could try that pulsed, solid state, UV you had a while back.

    ...Umm, yeah, what Steve said... and, while I don't pretend to be any sort of expert whatsoever on these, I can refer you to our experience with the one we used for a demo
    (for the FAA, no-less! ...my reply to similar questions, from 'GooeyGus':

    ...So, yeah, 5-10 Watts MIGHT start to 'tingle' the dye into lasing, depending on the 'mix', and age of the current 'batch' that is in it, but I honestly would not 'expect much', till you get into 12-15W +... Hope this helps...

    Well, shit, I guess that means I need to find myself a nice high power 532nm Q-Switched system

    Isn't there a 'ProDJ' somewhere with one of those? I guess that may be coming available soon

    If, for some reason, he can't (already modded or whatever...) we've got one down here, still in 'med-condition', with all the interlocks / proper fiber for the 600 - same one we used for that demo... so, ready to 'plug and play'...

    ..But see if Kev can help ya first... he's just a tad closer...

    peace..

    Jon,

    Do you have a service manual for this dye unit?

    No, but whattaya need to know? I got a pretty-good overview of 'tech-care' from the seller... I'm gonna guess you're wondering about 'error codes'?
