摘要：

We study the second harmonic generation (SHG) in a suspension of small spherical particles confined within a slab, assuming undepleted pump and applying (i) single scattering approximation and (ii) diffusion approximation. In the case (i), the angular diagram, the differential and total cross-sections of the SHG process, as well as the average cosine of SH scattering angle are calculated. In the case (ii), the average SH intensity is found to show no explicit dependence on the linear scattering properties of the suspension. The average intensity of SH wave scales as I(0)L/Lambda(2) in both cases (i) and (ii), where I(0) is the intensity of the incident wave, L is the slab thickness, and Lambda(2) is an intensity-dependent "SH scattering" length.
