'''<big>5/22/14</big>'''
I think the mode matching calculation I did was wrong because the value <math>I_R/I_{in}</math> should definitely just be 1.01/1.21. When I looked at the reflected beam I was just using one of the photodiodes from the analyzer so it's possible that messed up the measurement. I will try to look at the cavity dips before it goes through the beamcube and redo the calculation. Regardless of what the calculation says, the amount of green we were generating is promising.
Today there were two extra peaks showing up that I couldn't get right of. One was the same height as the 0,0 mode and the other was less than 25% of the 0,0 mode. The usual alignment procedure didn't solve the problem. Moving around the mode matching lenses didn't help much either. I checked the laser on the spectrum analyzer (which is currently not working great), and the wavemeter. Both seemed to indicate it was single mode.
