I've asked this on other forums and never gotten a good responce, I'm wangint to take a half-dozen diodes and combine their beams into one high-pwoere laser module. The only trick I've seen for this in a "flashlight" (I want it portable, not a labby with a fixed focal-length from jsut aiming hte alsers together) is to use 1/2 mirrors and keep firing the lasers through.
What kind of loss would I get from this? if I started with (for simplicity's sake) a 100mw diode, how many mw woudl escape? 95? 90? 50? keep in mind I will be stacking these, so the back diode will be passing through atleast 4 if not 6 1/2 mirrors and the first one will simple be reflecting from one.
Any better ideas of how to build a portable hgh-pwoered laser? people talk about beam combiners but nobody ever explained how they work, so I'm in the dark. I thought I could aim all the lasers at one point at the lens and it owuld focus them out in one beam, but I was told this didn't work (just verifying)
My aim is to first build a 1watt laser and eventuallly built a 2watt or more. --- for under $200 ($20 each for 200mw DVD burners, so 5x of those is 1W, 10X is 2W)
