    Has anyone played with the sharp gh0631ia2gc?

    I'm planning to build it in an stainless steel "sanwu pocket" style host with a 12mm axis module and want to overdrive it to 250mw instead of its 185mw raiting ,my question is , do these diodes run hot? I would assume not since is an single mode Same question for the 405nm bdr-206 ,I will run...

    Purple 405nm 1.6w or Green 525nm 1.2w (Sanwu Lasers)

    I looked on sanwu lasers at the new rangers series and can't decide witch one to by(the green option is 60 dollars more expensive),all I know is that the 405nm has a far more better divergence than the green one(I think that they are using an dpss diode) but the green one is far more vizible to...
