Ho:YLF amplifier with Ti:Sapphire frontend for pumping mid-infrared optical parametric amplifier

Abstract

We present a Ho:YLF Chirped-Pulse Amplification laser for pumping a longwave infrared Optical Parametric Chirped Pulse Amplifier at a 1 kHz repetition rate. By utilizing a Ti:Sapphire laser as a frontend, 5-μJ seed pulses at 2051 nm laser pulse are generated in a Dual-Chirp Optical Parametric Amplifier, which are amplified to 28 mJ pulses with a pulse duration of 5.6 ps. The scheme offers a potential driver for two-color (800 nm and 8 μm) high harmonic generation with an increased keV X-ray photon flux.
