Despite my discouraging post, I have high hopes for these MEMS. Here is why. They have rated power handling something like 25W/cm2. That's 50W for their .95" HD chip and that's spec and when do we stay strictly spec. At spec and with balanced white light that's 35,000 lumens and that's just about the output of the world's most powerful DLP based projectors. The problem the manufacturers face is that they are limited to non-coherent (ultimately) light sources. We are not.Exactly because of what you are saying here it is a mystery for me how the DLP can ever be used for projecting laser, as the beams will only be "nice" at the focal plane.
I did think a bit about it after you asked about the Cas..s. I just can't imagine that DLP's can be useful for laserists other than for holographic films.
I have an Acer HD projector that outputs 4,500 lumens and when using the Pangolin video presentation option I can display any laser show through video and RGB projector side by side The 100,000KPPS DLP blows the laser away. This is a throughput 3,000 times what the laser can produce, but...BUT the video is very pale by comparison. Based on experiments the video is about as bright as a 500mW combined output laser projector.
The brightness could be increased further, much further than even the effective 35,000 lumens would suggest because unlike the continuous illumination (yes, I know about dimming) of a typical HID video bulb the laser would only heat when it was on. Modulated laser illumination would make the color wheel unnecessary and polarized laser light would substantially increase the contrast of the video image not to mention that alternating polarization would enable 3D.
So, rather than try to emulate a monolithic galvo set, a laserist might want to turn an average video projector into a powerhouse that complements a typical RGB laser show with an ultra high bandwidth source. Problem is I'm kinda busy right now, but you see why I'm excited about these possibilities and why I asked what you were thinking about doing with these Cas....s?
