High-Efficiency BiBO-Based OPCPA with ~2.2 mJ Output Pulses at ~2.2 μm Compressed to 25 fs

Abstract

3-stage BiBO-based OPCPA pumped by ~1.2 ps, ~10 mJ pulses at 1030 nm from Yb:YAG laser provides ~2.2 mJ, 25 fs output pulses at ~2150 nm after compression with a pump-to-signal conversion efficiency of ~27%.
