Watch this video on PBS cubes on Metacafe "RGV Laser Optics" it is pretty good! Does anyone on this forum have any PBS cube videos that are informative and interesting to watch? If yes please post them! Is it hard to line up two lasers into one beam usig a PBS cube? I would like to take 2 650 red nm LOC laser diodes and join them to get 600mw of burning power! Is it hard to do this?
