Moar Modes

Sure enough, the problem with the poke matrix in this new configuration was caused by the beam size. With the bias voltage the beam was much more compressed than with a general random command. So when the bias wavefront was subtracted from the residual wavefront to get a measurement of the DM phase, it was only modifying the center of the residual.

I fixed this by adjusting the optics to make the beam larger when the bias is applied, something I probably should have done right away. The results look almost perfect, though slightly larger than before






Its possible I could make the modes even smaller by moving stuff around, but at this point I don't want to mess with it any more. I'll settle for Amish perfect.
