These include the temporal self-compression of a laser pulse in the filamentation mode, repulsive and attractive interactions of filaments, and influence of the birefringence on the filamentation. The propagation of femtosecond laser pulses at the 1550-nm wavelength in c-Si is studied for the first time using methods of time-resolved transmission microscopy. The nonlinear widening of the pulse spectrum due to the Kerr- and plasma-caused self-phase modulation is recorded.EnglishFemtosecond laser pulsesKerr effectFemtosecond filamentsCrystal siliconSelf-focusingSelf-phase modulationArticle10.15407/ujpe64.6.4572071-0194
