200-femtosecond pulses at 106 μm generated with a double-stage pulse compressor

Abstract

Starting with 90-psec pulses of a Nd:YAG laser, 200-fsec pulses are generated in a double-stage fiber-grating-pair pulse compressor. This corresponds to a compression factor of 450. A peak power enhancement of 16.7 from 480 W to 8 kW is calculated. The experimental results agree well with theoretical predictions.
