AbstractAbstract
[en] First experimental observation of the nonlinear diffuse scattering is reported. This new effect was observed in the propagation of the random-phased wave through a nonlinear dielectric medium. This effect is ascribed to the diffusion of the wavevector of the electro-magnetic wave to the lateral direction due to the randomly distributed nonlinear increase in the refractive index. (author)

AbstractAbstract
[en] The wavefront distortion of a large aperture (200 mm) laser beam from a high power glass laser system was directly measured using an interferometric method. The measured static and nonlinear wavefront distortions were used to calculate the intensity distributions at the far field and were then compared with the experimental data. The relationship between the wavefront distortion and the far field pattern thus established is very useful for characterizing the performance of the laser system. (author)
