Generation of Highly Directional Supercontinuum in Nitrogen
摘要
Abstract
The paper studies the conditions for the generation of a highly directional supercontinuum in a filament created in nitrogen gas by aberration focusing of radiation at a wavelength of 940 nm with duration of 70 fs and energy up to 7 mJ. It is shown that the spectrum of the highly directional supercontinuum covers the range from 350 to 1200 nm, its radiation divergence is diffractive, and its energy is 17 µJ.
