Progress in Soliton Dynamics in Hollow Capillary Fibres

Pulse compression and frequency conversion are key ultrafast technologies. Few-cycle near-infrared pulses, combined with conversion across the ultraviolet to infrared, have enabled femtosecond and attosecond pump-probe experiments, advancing the field of ultrafast science. Soliton dynamics underlie a new class of technologies which can bring important new capabilities to this field [1] . They provide access to even shorter driving pulses, with sub-femtosecond and sub-cycle pulse duration produced by self-compression, while maintaining high energy and peak power. They also provide a highly efficient broadband frequency conversion technique, generating few-femtosecond, µJ-scale pulses, tunable across the vacuum ultraviolet to near-infrared spectrum.
