    Specialties of specific wavelengths?

    I've been doing a lot of research of assembling a laser but I can't really decide what color to get. I've heard that blue lasers are the best at burning things up close, and that green lasers are best for a visible beam. What are the special notes for other colors/wavelengths?

    532nm vs. 520nm

    I'm thinking about buying from sflasers.us but the model I wanted is out of stock. So I contacted the guy, and he says that all custom green lasers are 532nm instead of regular 520nm. Is the 532nm less visible? I don't really care all that much about the IR leakage, but I might as well take...
