Bright extreme-ultraviolet high-order-harmonic radiation from optimized pulse compression in short hollow waveguides
Bright extreme-ultraviolet high-order-harmonic radiation from optimized pulse compression in short hollow waveguides
Multimodal nonlinear propagation dominates the evolution of intense laser pulses propagating in high pressure gas-filled capillaries used for high harmonic generation. A fully multimodal nonlinear propagation model is used to predict pulse evolution along such a capillary, and the length and pressure distribution optimised to produce the shortest pulses at the capillary output. This optimisation is shown theoretically to result in self compression of the pulse from ~53 fs to ~7 fs, and shown experimentally to increase the flux of high harmonic radiation from the capillary by an order of magnitude over comparable capillary and gas jet designs.

Abstract
Multimodal nonlinear propagation dominates the evolution of intense laser pulses propagating in high pressure gas-filled capillaries used for high harmonic generation. A fully multimodal nonlinear propagation model is used to predict pulse evolution along such a capillary, and the length and pressure distribution optimised to produce the shortest pulses at the capillary output. This optimisation is shown theoretically to result in self compression of the pulse from ~53 fs to ~7 fs, and shown experimentally to increase the flux of high harmonic radiation from the capillary by an order of magnitude over comparable capillary and gas jet designs.
