100 mJ infrared femtosecond pulses generated by dual-chirped optical parametric amplification

Abstract

We generated 100 mJ infrared pulses using dual-chirped optical parametric amplification (DC-OPA), which is the highest energy ever reported for an infrared femtosecond laser source. These pulses are very useful for strong-field physics research and energy scaling of sub-keV soft X-rays by high-order harmonic generation.
