Abstract

The amplification of light signals (angular frequency ωS in some isotropic media (D2O, fused silica, and Schott type SF10 glasses) by noncollinear phase-matched parametric four-photon interaction ω12→ωS1 is studied theoretically. Computer simulations are carried out for fundamental and second-harmonic pump pulses of a mode-locked Nd: glass laser. Degenerate interaction (wavelength λ12=1054nm or 527 nm) and nondegenerate interaction (λ1=1054nm, λ2=527 nm are considered. Characteristic phase-matching parameters and gain parameters versus wavelength are determined. Limitations by spectral bandwidth, optical absorption, optical damage, self-phase modulation, self-focusing and stimulated Raman scattering are analysed.
