New photo cathode laser system delivered from MBI

A newly developed photo cathode laser system providing rectangular shaped flat-top laser pulses with small (~2ps) rise/fall times, as well as a corresponding pulse shape measurement system (OSS) was delivered and installed at PITZ. In order to guaranty a good laser stability, a new acclimatisation system was installed in the laser hutch.
