A criteria for development of multidimensional solitons in saturable media was developed. As a benchmark saturable Kerr media, nonlinear glasses were considered, and an analysis of the effects of nonlinear absorption on soliton formation was done. The conditions for the soliton formation were usually expressed in terms of the normalized energy content, and also converted into dispersion and diffraction lengths. Due to the nonlinear loss in glasses, while a well-defined window of parameters exists for two-dimensional solitons, for their three-dimensional spatiotemporal counterparts such a window does not exist.
