Phase Matching and Quasi-Phase Matching of Extreme High-Order Harmonic Generation3 ìm, we extend full phase matching of high harmonic generation in argon and neon to 100 and 200 eV respectively, well beyond the phase-matching limit for 0.8 ìm. Also, we show that multiple weak quasi-CW waves can induce phase modulated structures in the high-harmonic generation process that can be used for highly efficient quasi-phase matching.

Sub-100-as soft x-ray pulsesWe demonstrate the generation of powerful sub-100-as soft x-ray pulses by means of 1.5-cycle waveform-controlled laser fields. Our new tool opens the door for exploring electronic processes on a time scale approaching the atomic unit.

Quasi-Phase-Matched High-Order Harmonic Generation in the Soft-X-ray RegimeWe realized quasi-phase-matched generation of soft x-rays emitted from two gas jets. The harmonic signal has been enhanced in a broad range (from 250 eV to 600 eV) and up to two orders of magnitude around 400 eV

Comparison of Parallel and Perpendicular Polarized Counterpropagating Light for Quasi-Phase-MatchingThe effect of the polarization of counterpropagating pulses on suppression of high harmonic generation is investigated. The results agree well with simple models of harmonic suppression and have application to quasi-phase-matching of harmonics

Enhanced Harmonic Generation in Gas Jets with Expanding ClustersWe report femtosecond-time-resolved enhancement and anisotropy of thirdharmonic generation in highly ionized clustered argon at intensities exceeding 1015 W/cm2.Results suggest a path to phase-match high-order harmonic generation in dense plasmas withultrahigh intensity.
