Using
equations governing the variation of the beam size and the curvature of wave front in the
logarithmically saturable nonlinear media, the Gaussian-type breath mode of spatial
soliton has been described in detail. With the aid of a potential method, the positive and
negative signs can be assigned to the first order derivative of the beam size with respect
to the propagation distance. Thus, important parameters of the breath mode, such as the
beam size, curvatwre radius of the wave front, the period, etc., have been calculated. 相似文献
