摘要：

We report on the operation of the Mercury laser with fourteen 4 x 6 cm(2) 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, (2 x 10(5) cumulative shots) with over 80% of the energy in a 6 times diffraction limited spot at 1.047 mu 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.
