Notes
1. After 30 minutes warm-up in the temperature range 20 - 35 °C, temperature change < 1 K/h.
2. Position and angle of static alignment tolerances are specified with regard to laser beam exit.
3. The exit window is equipped with the Manual Window Shifter (MWS) in case of external photo contamination. This laser system is not equipped with the Automatic Crystal Shifter (ACS) due to the lower power densities on all internal optical elements.
