diff gain: 23 turns
aux gain: '--', 'low'
Saw green from the HeNe!!!
I'm getting about 0.71 mW incident (chopped) on the cavity and about 0.56 mW inside. I couldn't detect a signal from the green, but it was very faintly visible after the diffraction grating. This is good, but the orange laser is not a whole lot more powerful. If I can't detect the modulated narrow frequency light from the HeNe, the orange laser isn't looking too good. I'm getting ~12mW chopped power incident on the cavity from the orange laser (with the thermal head centered at 1024) and about 2mW inside :-/
