Abstract
We wish to propose in this paper a new mechanism of the self-focusing of laser beams in semiconductors which rests on the energy-dependent scattering of carriers. While this is the only important mechanism of self-focusing in elemental semiconductors, our elementary analysis of the effect reveals that it can be of comparable significance with the one recently proposed by Tzoar and Gersten in nonparabolic semiconductors.Keywords
