PSL installation team

The fiber bundles are now reassembled to the high power oscillator and the beam path through the high power oscillator box had been aligned. All laser crystals had been cleaned (we found minor dust particles, which could easily be removed). Crystal #3 had been replaced with a spare part, because a spot had been found on the pump side. (NOTE: The LRA must sit at it's reference position, if the oscillator and/or the frontend is turned on.)
We reinstalled the laser crystals after cleaning, but the system had not been turned on yet.
