New Mid-Infrared Light Sources

We present a novel mid-infrared (mid-IR) source of ultrashort pulses applicable to a wide range of biological, spectroscopic, and strong-field physics investigations. The source produces 67 fs pulses at 3.2 microns, with energy of 3.8 μJ at 100 kHz repetition rate and a pulse-to-pulse RMS stability of 0.7%. The system is based on OPCPA, is scalable in energy and repetition rate, and provides a platform for a new generation of ultrashort mid-IR sources.
