| Abstract: | Based on the transform of phase aberrations in third harmonic generation, the focusing properties of third harmonic beam with nonlinear crystals having periodic surface ripples were theoretically investigated. A diffraction model has been developed, which can analytically calculate the intensity and angular distributions of multi diffraction orders. It provides the design criteria for the third harmonic generation of high energy laser drivers. |
