COMPUTATIONAL MODELING OF SUPERCONTINUUM GENERATION IN FUSED SILICA BY A FEMTOSECOND LASER PULSE OF A FEW OPTICAL CYCLES

摘要

The numerical solution of a wave equation describing the propagation of the laser pulse of a few optical cycles in fused silica is obtained. Our numerical simulations closely follow the published experimental data. A shifting of the spectrum peak of the broadened pulse, depending on the input-pulse central wavelength, is observed.
