Quasi Phase Matching

We propose a novel optical parametric amplification scheme that combines quasi-phase-matching with a composite pulse approach that involves crystal segments of specific lengths. The presented scheme highly increases the robustness of the frequency conversion against variations of the nonlinear coupling and of the pump, idler, or signal wavelengths, and has therefore the potential to enhance high amplification and broadband operation. Simulation examples applied to LiNbO 3 are given.

Wave Vector Mismatch

We investigated the issue of parametric bandwidth for a collinear quasi-phase-matching (QPM) optical parametric amplification (OPA). Mathematical model for evaluating the parametric bandwidth tolerance of the OPA was derived by expanding the wave-vector mismatch in Taylor series and taking the first two terms into consideration for accuracy. Based on the model, the variation of pump acceptance spectral bandwidth with parametric wavelength was discussed. The correlating curve of the pump wavelength and the parametric wavelength was obtained for the largest pump acceptance spectral bandwidth. These results were compared to that obtained by numerically calculating the parametric gain curves of OPA when pumped with different Gauss bandwidths by means of three-wave mixing equations directly, and were found to be in good accordance. The results presented are helpful for specifying the optimal pump wavelength of the parametric amplification and oscillation.
