Abstract

A femtosecond light pulse at 480nm in wavelength was generated during filamentation of an intense 808nm femtosecond laser pulse propagating along the x axis and polarized between the y and z axes of a KTP crystal. It was proven that the parametric amplification process by a fourth-order nonlinear polarization (χ(4)(ω2,ω,ω,ω,ω1)) induces frequency generation at 480nm, where the pump light comes from the incident laser and the seed light comes from the generated supercontinuum by filamentation. The wavelength of the generated signal could be turned from 460 to 520nm by adjusting the propagation direction in the crystal.
