Co-Resonance temperature for OPO and much improved 6MHz beat note
I parked the temperature where seed and pump transmission had dual resonance (at 32.16 C). Later fine tuned temperature for best NLG while looking at CLF 6 MHz beat note level. The dual resonance for maximum CLF amplification is 32.06 C. The dual resonance outside non-linear gain region for seed is 41C.
The CLF 6MHz beat note is now at -10 dBm. The loop hasn't been characterized yet.
