Нелинейные оптические явления в прозрачных средах

Abstract

Experimentally studied the broadening of the spectrum in the post-filamentation channel of femtosecond laser pulses with a central wavelength of 940 nm. Preliminary estimates and experiments show that the main process leading to the broadening of the spectrum was fourwave mixing of the original pulse components. The process of phase self-modulation was also considered. The spectrum width in the experiment was 400-1000 nm. The possibility of creating a white supercontinuum source for atmospheric sounding has been demonstrated
