Wow! Seriously, wow. I think Dr. Sam might like to see that photo.

well frankly it looks good, but its still only doing a bit of what it is supposed to do. I've been talking to sam about it. it seriously is not an amateur's laser. everything has to be literally perfect or you get nothing at all. i'm only getting about .3-.4mW out the OC end depending on cleanliness. I should be getting closer to a 1mW according to Sam. after a matter of seconds to a minute the power declines rapidly from .42 to .30mW from dust piling up on the optics and unlike red, the gain is so low (about 1/23rd that of red) that lasing weakens and can even cease entirely, unlike red and the other colors which just turn their nose up at the dust. it has to be utterly PRISTINE to even have a hope of seeing it work.
