Abstract
We report on the operation of the Mercury laser with fourteen 4
6 cm2 Yb:S-FAP amplifier slabs pumped by eight 100 kW
peak power diode arrays. The system was continuously run at 55 J and
10 Hz for several hours, (2105 cumulative shots) with
over 80% of the energy in a 6 times diffraction limited spot at
1.047 
m. Improved optical quality was achieved in Yb:S-FAP
amplifiers with magneto-rheological finishing, a deterministic
polishing method. In addition, average power frequency conversion
employing YCOB was demonstrated at 50% conversion efficiency or
22.6 J at 10 Hz.
