Laser light scattering and absorption in dense, spherically symmetric plasmas
- Univ. of California, Davis, CA (United States)
A computational study of the interaction of a focused laser beam with a dense, spherically symmetric plasma is undertaken. The plasma is treated using linearized fluid equations for the electrons with the ions assumed immobile; the electromagnetic field is determined from steady state solutions to Maxwell's equations in spherical coordinates. Energy dissipation in the plasma occurs as a result of Inverse bremsstrahlung collisions and resonance absorption. The scattered field distribution and the spatial variation of the fields and energy deposition within the plasma are found for various laser-plasma configurations and the applicability of the theory as a function of plasma temperature and laser power is determined with a self-consistent analysis.
