Numerical simulation study on distinguishing nonlinear propagation regimes of femtosecond pulses in fused silica
Abstract We perform numerical simulations to investigate the nonlinear propagation dynamics of femtosecond Gaussian and vortex beams in fused silica. By analyzing the extent of spectral broadening, we are able to distinguish between the linear, self-focusing, and filamentation regimes. Additionally,...
