Abstract

By numerically solving the Kirchhoff-Fresnel integral equations, the effects of temporally varying phase distortions on the beam quality of a four-wave mixing MOPA system were investigated. Our simulation revealed that the performance of such a four-wave mixing MOPA system depends strongly on the percentage of the overall power impinging on the active area of the phase conjugate mirror. Additionally, the onset time of the laser-induced medium perturbation was calculated for a set of different gas mixtures and a range of output energies. The phase distortions produced by the transit of a shock wave orthogonal to the optical axis could be completely cancelled by the phase conjugate mirror, i.e., no effect was found when comparing the far field distributions at different times during passage of the shock wave through the mode volume.
