Thinking about doing 1 standard 9mm, and 1 - 6 Watter to keep costs down. Not sure how that would work. I'm also not sold on the 6 watters bad divergence. I have lots, and lots of options, and may start a poll looking for suggestions. The third hole will probably be filled with a red targeting lazer due to the difficulty of merging 3 beams of the same wavelength, which would requires knife edging. I'd rather have 2 overlapping beams, than 3 stacked, and I don't think this design will lend itself to easy knife edging?Looks awesome. Somebody NEEDS to pack 3 of the 6W diodes in this. A realistic 15W handheld laser would be killer....on your batteries and wallet lol. Still, would be awesome. And the simple fact that it is possible means someone must do it.
