    The most beautiful wavelength?

    The most beautiful color is from tunable optical parametric amplifier:D But I guess it goes out of the question, so green color all the way 532 or 515 coz my eyes are most sensitive in that region.

    Need a cheap, high stability laser

    I need it darn cheap so gas laser and all the other cool stuff like Nd:YAG, Ti:Al2O3 are out of the question. I'm not going to do it blindly:] and yeah I will tell you how it went. Maybe if I will not be lazy I will even get a profile of the beam and measure the stability with ophire.

    Need a cheap, high stability laser

    Hmm your idea with lowering the voltage might just work. Because I really don't need allot of power for testing photodiodes.

    Need a cheap, high stability laser

    Have you had any experience with cheap china laser, are they stable? It doesn't matter for me if the output is very low all I need is stable intensity, coherent light source. Any suggestions are welcome. P.S. I would prefer red or green.
