Subject: temperature setting for PSL doubling crystal 

I fixed the temperature control of the oven for the PSL doubling crystal.
The PID settings were not good, and also, TC200 was beging DETUNED. So, I activated TUNE function and adjusted PID settings.
I'm not sure what the DETUNE function is for. The manual can be found here;

Current settings for Thorlabs TC200 are (Red ones are what I changed from the previous setting);

parameters Xend Yend PSL
TEMP SET (deg C) 37.5 35.7 36.9
P 250 250 250
I 60 60 200 (was 117)
D 25 25 40 (was 19)
(DE)TUNE on? TUNE TUNE TUNE (was DETUNE)
TMAX (deg C) 200 200 170
PMAX (Watts) 18 18 18
