Laser field effects on the collective inverse Bremsstrahlung process
Abstract
The energy loss method has been applied to a large variety of transport problems in optics, solid state and fusion research. Usually, the transport equations are linearized, so they cannot deal with the multiphoton interaction in the presence of an intense laser field. In particular, not much attention has been given to collective contribution to the rates of the energy loss and inverse Bremsstrahlung process from a quantum mechanical viewpoint. On the basis of the center of mass approach, we show the proper way to calculate the collective part of these rates, which depend on the energy loss function Im(-1/episolon(q vector, omega)).
