We have 0.77mW on the IR PD before the SHG, with 30dB of gain we get 0.21 Volts. With 2k transimpedance this means the responsivity is 0.0041A/W (this seems too low). We are getting 21mW onto ISCT1 from the PSL, meaning that the BS is 4% reflective, the same value we measured durring HIFO Y.
21 mW is not enough for us to get a decent amount of conversion to green. Right now we are getting about 2.5uW of green out of the SHG, not really enough to optimize the alignment.
