Chiller settings changed:
The diode chiller seem to have all of a sudden a higher flow than last week. We got 31.2 lpm at fully opened chiller bypass. Since the chiller's flow interlock triggers at 30 lpm this threshold needed to be reset to 34 lpm. We recomment to reset it to 30 lpm if the flow decreases (ask LZH for technical password).

HPO alignment (see laser manual for detailed alignment procedure):
Multimode alignment (freerunning oscillator, without seed from MOPA, without 4f lenses: 62.2W @ 32 A pump current per crystal and radially symmetrical beam profile)
Fundamental mode alignment (4f lenses / pump light), HPO still freerunning (output in both directions): 160 W @138W pump power per laser crystal.
Next step: injection locking

Calibration of FE PDs:
We set the calibration value for the photodiodes inside the MOPA box (for pump powers and powers behind the 1st, 2nd, and 
3rd amplifier stage) to 100 via the Beckhoff laser control screen.
