After optimizing the injection locked laser system on Monday, we operated it also over night. We will keep the external shutter closed at the times nobody is inside the LAE, so that the light is dumped on a power meter inside the oscillator box, until the flow watchdog for the external power heads is installed. The power and flow watchdogs for the laser are already working.
The path towards the high power PMC is aligned and we are currently working on the alignment of the ISS AOM. When this is finished we can increase the power in this path as well (at the moment the light is dumped on at a variable attenuation unit that is placed directly outside the high power oscillator box).
During calibration of the Diagnostic Breadboard (DBB) we figured out that one PZT used for the autoalignment to the modecleaner is broken. So we had to replace that with a spare one and starting the calibration all over. Currently we are still in that process so that the DBB is not operational at this time.
