Nonlinear Spectroscopy With Few-Cycle Pulses In Mid-Infrared: Mapping The Electron Band Structure By Intraband High-Harmonic Generation In Solids
2017 CONFERENCE ON LASERS AND ELECTRO-OPTICS EUROPE & EUROPEAN QUANTUM ELECTRONICS CONFERENCE (CLEO/EUROPE-EQEC)(2017)
Abstract
High-order harmonic generation (HHG) in atomic gases is one of the key phenomena in strong-field laser-matter interactions, playing a central role in optical physics and rapidly growing attosecond technologies. When applied to solid materials [1-3], approaches of strong-field physics are subject to natural limitations, related to absorption and much lower laser damage thresholds of solids. As a reward, such solid-state extensions promise breakthroughs toward petahertz solid-state optoelectronics, open avenues toward attosecond science on the platform of solid-state materials, and suggest new all-optical methods for crystallographic analysis.
