Optical field distribution on a hohlraum wall during indirectlaser-driven inertial confinement fusion
Abstract
A model to calculate the optical field distribution of quadruplet beams on a hohlraum target wall is pre-sented. This model combines geometrical ray tracing, coordinate transformation, and Fresnel diffractionintegral to capture the quadruplet beams propagating in four different directions and the typically non-planar geometry of the hohlraum wall. The results demonstrate that the optical field distribution arisesmainly from individual beam diffraction, and the interference with other beams in the quadruplet hardlydevotes to the distribution. A movie is also produced to interpret the spatio and temporal evolution ofthe optical field on a cylindrical hohlraum wall.
