Cavity-Enhanced High Harmonic Generation for Attosecond Dynamics at Surfaces
Abstract
Supported by the AFOSR, we have worked on the development of high repetition-rate sources of vacuum ultraviolet and extreme ultraviolet (XUV) radiation for photoemission experiments. This effort has had three main thrusts: (1) The refinement of Cavity-Enhanced High Harmonic Generation (CE-HHG) to be a usable light source for 100 ts-resolution photoemission experiments. (2) The investigation of incorporating gating schemes into CE-HHG to produce attosecond pulses. (3) The development of a high-average power mid-lR frequency comb for driving harmonics in solids. Effort (2) led us to the conclusion that CE-HHG was not the best way to achieve high rep-rate attosecond pulses and Efforts (1) and (3) have led to further ongoing work including pursuing single-pass solid-state HHG for high repetition rate isolated attosecond pulses.
