Laser Radiation Forces: Generation of and Dependence on Magnetic Fields
Mechanisms are described through which the high frequency-fields of the laser beam can directly exert time-averaged forces on the plasma. The generation of magnetic fields by these radiative forces is discussed and shown to depend on the field momentum transferred to the plasma during absorption. Refraction is used to illustrate the dangers of approximation. The magnetic field itself is shown to be responsible for a large, polarization dependent radiative force.
