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 th
e logarithmic type. The conditions necessary to establish these solito
n states as well as their associated characteristics are discussed in
detail. Pertinent examples are provided to elucidate their behavior fu
rther. (C) 1997 Optical Society of America.
