That's right. These are too expensive to do the needed work (just like the 4W C-mounts). They are based on a strained lattice GaN and to extract that power must resort to multimode producing, maximum cavity volume utilization within the junction and therefore will probably work more like the higher power 445 multi-modes than the single modes. But, if I remember correctly these were much less robust to temperature rise than the blue GaN diodes. So, they may not overdrive as well. At these prices NO ONE is going to drive them hard. At these prices I would be a little nervous each time I switched on the projector fearing... no-green.
An interesting thing for me is that even though I like experimenting, the turn key green source in my current projectors has always meant quick progress (a few saved steps). So, when these diodes drop to say $200 or less a diode then I'll get a couple and wring them out optically and thermally and look to add them to an existing projector or to build a new all direct diode unit. My current projectors are not bulky because of the green. It is the sum of the power supplies, the cooling and the beam manipulation including the scanning system as well as the green and with the color correction board the colors are REALLY nice.
I followed your advise, Dave and got a pretty good deal from Laserwave. I pushed them relatively hard and so I am loosing a little on this distribution, but not all that much. However, there are going to be some pretty accelerated projects coming out of this, so that's worth it.
