High-power picosecond laser pulse recirculation

Abstract

We demonstrate a nonlinear crystal-based short pulse recirculation cavity for trapping the second harmonic of an incident high-power laser pulse. This scheme aims to increase the efficiency and flux of Compton-scattering-based light sources. We demonstrate up to $40\times$ average power enhancement of frequency-doubled submillijoule picosecond pulses, and $17\times$ average power enhancement of $177\mathrm{mJ}$, $10\mathrm{ps}$, $10\mathrm{Hz}$ pulses.
