OPO green loss
It's lossy. 3% 0.16%
Final correction for MM subtraction. Now subtracted MM off the on resonance dip.
1.06% LOSS
[Edited after some input from Terry, Sheila and Daniel]
Calculation:
rloss = 0.99467
Amplitude loss t_L = sqrt(1-rloss) = 0.1031
Power loss L = 1-rloss^2= 0.0106
Here's what we have:
70% mode matching calculated from transmission (00 peak/all peaks = 0.06/0.0856 = .7)
Mode mismatch power = (V off resonance)*(1-.7) = 0.108 V
This yields our green dip to be 89.6% of the off-resonance power ( (0.36-0.108) - (0.134-0.108) ) / (0.36-0.108)

Shouldn't the MM part be subtracted from both the incoming and the reflected light? What is the corresponding round-trip crystal loss?
