SHG characterization
We measured the output power of SHG (green) with respect to the LiNb temperature and the input power (IR). A figure attached shows a result. The x-axis of the right graph remains to be converted to actual temperatures (we don't know the name of the thermistor we are using at this moment).

I did the SHG output power vs input power measurement again. I used HWP and FI pair after the main laser to change the input power in order not to get mode-hops. During the measurement, the current value of the main laser was 2.004 A. The SHG crystal temerature was 3.170 kOhm.
