Abstract
A theory of self-focusing of laser beams in semiconductors in a homogeneous magnetic field is presented. The focal length and beam profile are calculated as a function of the magnetic field strength and the laser intensity. We find that a much smaller light intensity is needed for self-focusing when the cyclotron frequency approaches the laser frequency.Keywords
