I *did* find a better laser than the one I originally asked about, a Uniphase 2214-25MLUP, and I found a power supply that's actually designed to work with it. One simple question, though. The literature on the series of laser this laser falls into lists the wavelength for this laser as 458 to 515. Does that mean I can adjust it to get either, or does that mean that there's a chance I would be getting a green laser? There's another one I can go with if this one isn't the color I want, but this one is slightly cheaper. Thank you for your help. To let you in on a secret (well, not really, since he mostly knows), it's a gift for my laser-loving boyfriend.
