    Default Green Laser crystals.

    I need to know where I can buy those crystals in lasers that turn 808nm into 1064nm, vanadate I think that can handle 2W of 808nm,and those crystals that turn 1064 into 532nm Ktp I think that can handle 2W of 1064.

    If 2W crystals are too expensive, where can I buy crystals that will give me the most out <2W for UNDER 70 USD and what I will have adjust the power of the IR too?

    Before getting yourself into this field, keep in mind that building a DPSS laser is not easy! If your aim is to save money, I would recommend buying a finished laser instead. If you really are interested in building a DPSS laser as a learning experience, I recommend you start by trying to fix a broken one. They can be had rather cheaply and, if nothing else, provide a good source for spare parts.

    I'm just gonna use some helping hands to hold the 2 crystals and focusing lens in place and shine my laser through them, i'm NOT trying to build it into a handheld.

    That probably won't work too well.

    the crystals and diode will need cooling, otherwise the diode will die and the crystals will get COOKED . So holding them for any long period of time using helping hands isn't a good idea. You really need proper mounts.

    I never said anything about a handheld. In fact, this is the wrong forum for that... We're no pointer jockeys.

    Anyway, the cavity of a DPSS laser is not really as simple as 1-2-3. There's a lot more to it and I highly doubt you'll get much, if any, green light out of just placing an Nd-glass and KTP crystal in series using a pair of helping hands. You are very welcome to try though, but I sure hope you're wearing a good pair of laser safety goggles around that much IR.

    Ok then I'll just forget about it.

    If you really want to do this, buy one of those bonded crystal sets where the cavity one complete unit and all you have to do is shine 808 into them. Super easy and they're like $50.

    Helping hands wont work.... for the OC mirror alone you're going to need a 3-axis (minimum) adjustable mount. If you are off by a fraction of a mm you wont get any lasing, hence why the helping hands wont work. Not stable enough at all.
