    cheap efficient lasers

    thanks for the help... I'm after a cold light source, hence my point about efficiency, since, for example, 75 watts input with 1 watt output means I'm losing a lot of power as heat... so far as spot size goes, I want something that I can vary with fisheye lenses, which is why i wanted a laser...

    cheap efficient lasers

    for cost, I'm looking in the order of hundreds of pounds/dollars, rather than around the 20000 mark...

    cheap efficient lasers

    sorry for cross posting, didn't know, won't happen again... efficiency is a primary concern, since 600w input to gain a milliwatt out is not my idea of energy efficiency, I'd prefer a more even balance.

    light sources

    by cheap I'm looking in the order of hundreds of pounds/dollars rather than thousands. The efficiency of most solid state lasers is in the order of 0.01%, I'd like to waste less energy than that...

    light sources?

    does anyone know of a cheap efficient (ideally greater than 80%) light source? I'm after one for UVa 315-450nm and one for green light at 520nm +-20nm. The ones I have looked at so far are neither cheap nor efficient. I need a fairly intense source preferable (in the order of watts rather than...

    cheap efficient lasers

    does anyone know of a cheap efficient (ideally greater than 80%) light source (preferably laser)? I'm after one for UVa 315-450nm and one for green light at 520nm +-20nm. The ones I have looked at so far are neither cheap nor efficient. I need a fairly intense source preferable (in the order of...
