摘要：

An analytical treatment of rotating elliptical gaussian beam propagation in nonlinear media is presented. It is shown that the self-focusing threshold depends on the parameter specifying the beam rotation and is higher than for the beam without rotation. It is established by the following rule: the greater the difference between the light beam and the axially symmetric one, the higher the threshold power needed for its self-focusing.
