seen this? sonys 21watt rgb

surprised no-one has posted this yet, however it says 40mrad Divergence angle (horizontal)

The newly developed RGB laser module uses semiconductor diodes for the red and blue lasers, and a compact, high power solid-state SHG*2 laser for the green. Both the red and green lasers were developed internally by Sony. The three lasers generate output power of 10W for red, 6W for green, and 5W for blue, resulting in a total of 21W. Furthermore, energy conversion ratios for the lasers range from 15 to 22% (18% on average), representing extremely high efficiency for power visible lasers. This high energy conversion ratio also realizes low energy consumption within the module itself.
This module can be used as the light source for a range of projectors, from 1,000 lumen home theater projectors to 10,000 lumen large screen projectors

40mrad.. i wonder what the beam size is at the aperture...

[Eidetic]

I wonder if all three beams have matched diameter and divergence. You'd think a company like Sony would design the module for easy and efficient coupling to an optical system. Laser companies generally leave beam shaping to the product integrator. I hope Sony hasn't. It would certainly make my job easier!

I'm more impressed by this:

Wavelength 642nm 532nm 464nm
464nm in a direct diode blue? I want one!

464nm in a direct diode blue? I want one!

holy crap you and me both, that sounds like a sweet color

[krazer]

The divergence is clearly not matched, ranging from 35-40 for the different colors. Also, its hard to say, but I would bet the output isn't a single beam, but rather red, green, and blue beams ready to be sent to your DLP chips. This module ain't designed for vector scanning...

edit-I would expect the 564 to be correct, Nakamura's (the founder of Nichia) startups have shown diodes as far out as 520nm
