Three-dimensional modeling of the laser radiation absorption in the geometrical optics approximation
Abstract:
The paper describes a mathematical model and algorithm for simulation of laser radiation absorption by plasma target in the geometrical optics approximation. An analytical solution of the differential equations assuming a constant gradient of the square of optical coefficient in the cell is proposed. A numerical calculation algorithm is developed, and estimation of its convergence has been done. For a partial accounting of effects that are beyond the geometrical optics approximation, one-dimensional model of the layered medium was used.
