Nonlinear pulse compression of 515 nm pulses toward 20 fs and its application in all-solid-state high-harmonic generation

Abstract

<p>To capture the dynamics of light–matter interaction, intense ultrafast pulses are required. In this study, we present an all-solid-state nonlinear pulse compression setup that successfully compresses the second harmonic of 1030 nm, centered at 515 nm, from 189+- 19fs to 25+-3fs , using self-phase modulation in a few pieces of fused silica plates. The M^2 measurements show near-perfect beam quality with M^2x and M^2y being 1.16 and 1.17, respectively. We performed all-solid-state high-harmonic-generation measurements following this configuration. This work demonstrates industrial-graded all-solid-state high-harmonic generation in the extreme ultraviolet regime.<br></p>
