Single resonant parametric oscillators including intracavity quadratic and
cubic nonlinearities are described in the mean-field limit with a cubic and
quintic complex Ginzburg-Landau equation. Following our model, simple desi
gn criteria are derived for the generation of solitonlike pulses and beams
for singly resonant optical parametric oscillators. (C) 1999 Optical Societ
