Installing laser beam stabilization equipment

Dr. Bernd Schaefer came to help us install the equipment of laser beam stabilization today. I will assist him. I ran the TWIN excimer amplifier, its output energy reached ~30 mJ. By sending less than 1% transparent beam behind a reflected mirror to the equipment, we could monitor the laser beam profile. The problem is after the same ND filter the transparent of seed beam is too weak compared to the pre-amplfied beam.

The computer was sent from Germany, we could drive it by 115V power supply. I ordered a 110V 500W power supply for computer.
