Ho:YLF amplifier with Ti:Sapphire frontend for pumping mid-infrared optical parametric amplifier (2004.12648v1)

Published 27 Apr 2020 in physics.optics

Abstract: We present a Ho:YLF Chirped-Pulse Amplification (CPA) laser for pumping a longwave infrared Optical Parametric Chirped Pulse Amplifier (OPCPA) at a 1 kHz repetition rate. By utilizing a Ti:Sapphire laser as a frontend, 5-{\mu}J seed pulses at 2051 nm laser pulse are generated in a Dual-Chirp Optical Parametric Amplifier (DC-OPA), which are amplified to 28 mJ pulses with a pulse duration of 6.8 ps. The scheme offers a potential driver for two-color (800 nm and 8 {\mu}m) high harmonic generation with an increased keV X-ray photon flux.
