Abstract

It is shown that partially incoherent spatial solitons are possible in saturable nonlinear media. This is demonstrated by means of an exact Gaussian solution in the case when the saturable nonlinearity is of the logarithmic type. The conditions necessary to establish these soliton states as well as their associated characteristics are discussed in detail. Pertinent examples are provided to elucidate their behavior further.
