I *might* have built a 500mW Blu-ray-recorder-diode-powered violet (405nm) portable focusable laser... maybe. Capable of cutting through black insulating tape at 3m, you say? Possibly. And a 1.1 watt blue (445nm) Casio-projector-harvested-laser-diode-powered portable focusable yada yada capable of vapourising small mammals* at 300 yards**? Might have...
I might also have the heatsink machined for my 'HydraMag' which is a portable laser ("pointer" would stretching the definition somewhat) made from a 4xD-cell Maglite body, with 8 individually focusable blue heads.. total output 9 WATTS. Trying to figure a way of getting all the beams to converge on one point, adjustably, without having to take a degree in micro-optical engineering. I can visualise how to do it, just not how to MAKE what I can visualise :-/

* Full vapourisation may not occur.
** Actual vapourisation distance may vary.
