Quasi-phase-matching of harmonic waves in plasmas: Calculations, new schemes, and applications

Abstract

We review recent studies of the coherent phase matched conversion of ultrashort pulses in the modulated plasmas. Particularly, we discuss the influence of ablated and tunneled electrons on the quasiphase- matched high-order harmonic generation in laser-produced plasma and application of mid-infrared pulses for the quasi-phase-matching of harmonics in silver plasma. These studies demonstrate the perspectives of frequency conversion in properly modulated laser-produced plasmas.
