Abstract
We achieve a surprisingly exact agreement between the simulation results and the experimental observations (J. C. Travers et al. Opt. Express 16, 14435-14447(2008)) of visible supercontinuum (SC) generation pumped by a 400W single mode continuous wave (CW) fiber laser. The propagation of CW field in photonic crystal fibers (PCF) is numerically simulated by solving the generalized nonlinear Schrödinger equation with the adaptive split-step Fourier method for high accuracy; moreover, we apply the method of averaging the generated spectra in many simulations to approach the experimental results. Our simulations confirm that the extension of SC toward short wavelengths is due to the trapping of dispersive waves by redshifted solitons.
