Abstract

Results of supercontinuum generation experiments in case of excitation by optical pulses with central wavelength 828 nm, duration 40-50 fs, energy up to 1,0-1,5 mJ are presented. Supercontinuum radiation was detected in crystal DKDP and other crystals with χ⁽²⁾-nonlinearity at range from 400 nm to 1450 nm, as well as up to 2300 nm, where radiation within blue range 400-480 nm and IR-range 900-2300 nm was caused by parametric processes. Obtained radiation was analog of microstructured fibers supercontinuum radiation in the width of output spectrum.
