The hype is all over the blue, green, and violet lasers, neglecting the ol' red laser. I find the red lasers to be very amazing (the color and extremely thin beams of the single mode diodes) and I am trying to find the best diodes I could get my hands on (in terms of power, divergence, and beam specs). I've seen a few YouTube videos displaying a 4W 660nm laser.. If that is the highest-powered diode on the market, where could I get one? As of now I have only purchased diodes off of ebay.
