Abstract

We report on a side pumped Nd:Phosphate laser regenerative ampli er that delivers up to 100 mJ laser pulses in a single TEM mode. The laser beam is mode matched to the ampli cation medium thanks to an intra-cavity fused silica phase plate for mode shaping and a telescope for adjustment of the beam mode to the ampli cation rod section, so that most of the energy stored in the rod is transferred to the laser pulses. As a result of the good overlap and the low losses, an optical to optical conversion eÆciency up to 10 % was measured for a pumping current of 80 A and above 100 mJ output pulses.
