    i dont get it. Whats all the excitement about 671nm Has anyone reviewed the eye response curve recently. My eyes dont work out there, dont know about yours.

    Tight beam, high powers, great color depth

    I haven't seen it in person myself though

    So thin disk is just a very thin piece of yag (or vanadate, whatever they use in the 671's) with a high dopant level that is pumped like crazy and cooled very well, correct? Is there anything else inherantly different about thin disk lasers from conventional DPSS systems?

    Thin disk has the lasant as a spinning wheel, gets rid of a lot of problems in pumping the laser, getting rid of heat, getting rid of thermal lensing, and allows power scaling. I'm actually shocked at the poor m^2 number for the product, but it is a way forward,

    That 671 was for a medical demand to replace krypton in eye surgery and derm, and is much needed from the medical point of view. Keep in mind medical krypton used both the 647 and 676 lines.

    While 671 would not be my line of choice, it would not take long to rescale that to one of the other lower gain Nd:YAG lines and get the nicer red at 652 or so, or perhaps the other interesting colors possible by doubling the F manifold lines. In other words they figured out how to suppress 1064 from dominating the 1342 lines, which means they could get the 130x line, at a bit less power. And some other lines I'm not talking about.

    WOW then we could stick it into an aixiz module and make a pointer out of it and pop balloons and light matches?
