32.5 mJ high peak power kHz-level 1617/1645 nm Er:YAG lasers

Abstract

We present recent results on high energy, high repetition rate 1645 nm Er:YAG laser optically pumped by efficient Er-doped CW fiber lasers. Up to 32.5 mJ pulse energy, 0.85 MW-level peak powers are obtained at 1000 Hz. The results are presented in a wide 500-5000 Hz range of repetition rates.
