Abstract

This paper presents recent studies of the propagation of high-power laser beams like Laser Integration Line (LIL) and Laser Megajoule (LMJ) beams when interactions occur with environmental pollution particles. The studies are mainly achieved with the CEA-DAM MIRO beam propagation code. The highest intensifications in the downstream propagation are obtained for phase objects such as dielectric particles rather than for amplitude objects such as metallic particles. Dramatic amplifications of Kerr nonlinear effects both inside the component and at its rear-surface can occur depending on the particle size.
