GREEN
I still have problems in maximizing the power out from the doubler. I realized that the real green power I obtain is about 30 uW, and it is the power which really enters the Faraday.
Before I was measuring it just after the Harmonic separator, and there was some residual IR beam which increased the power on the power meter, that's why I obtained about 200 uW.
I also tried to slightly vary the position of the mode matching lens, but I was not able to get more than 30 uW on the power meter.
TRANSMON PATH
The 50 cm focal length lens has been added in the position shown on Manasa's layout, and the beam has been focused on the PD.
