Is this one of the diodes from the casio projectors, 1W 445nm? They are rather nice arnt they =) Plans here to make a nice looking benchtop laser? Looks like it, I like =)

Hi Dr.Spark

Excuse my ignorance- but is there a way to combine outputs of multiple diodes into one killer beam? I presume diodes would also need to feed a small fraction of their output into each other to acheive phase synchronization, but is it even physically possible to attain something like that with optics?

For their power those diodes seem to have excellent beam quality too. Is the beam perfectly round as it looks? I have a 1W IR diode here but it's emitter is so large it produces a square beam, hardly any use without complicated optics or yag rods to pump.

Yes there is.

Watts

Essentially what your do is line up the beams right next to each other in a dot matrix kind of thing. The beam gets fat though...

That's the guy who owns arctos lasers Link2 . IIRC, that one puts out 20 watts of RGB light and costs a good $30k Link2

Edit: Just remembered, the process is called 'knife edge mirroring' or something like that

the owner of a similar company (George Dodworth of lightwave international) demonstrated the power of one of those laser arrays to me by sticking his cell phone in it.
