Description

technical field [0001] The invention relates to a spectrum broadening device, in particular to a spectrum broadening device based on a large mode field antiresonant hollow-core photonic crystal fiber, and a method for using the spectrum broadening device. Background technique [0002] In recent years, with the development of strong field physics and attosecond generation, pulse stretching and compression has become a key technical method of pulse shaping, the purpose is to obtain ultra-short and ultra-intense laser pulses for bombarding gas targets to generate high-order Harmonics, which in turn generate attosecond pulses. The capillary quartz tube was chosen as an experimental optical waveguide, which has been widely used in the process of pulse stretching. Effective spectral broadening is achieved by sealing capillary quartz tubes and filling them with highly nonlinear noble gases (He, Ne, Ar, Kr, Xe). Self-phase modulation plays a major role in the overall broadening of...
