Obviously, one of these generation processes occurs with a big phase mismatching. We investigate comb generation efficiency in a dependence of the phase mismatching between interacting waves and other parameters. As a result, we observe various regimes of comb generation. It should be emphasized that we find out the generation regime with synchronic changing of the maximal intensities of all waves. At the same time, shape of the appearing sub-pulses at these frequencies are similar to Gaussian one.
Our consideration is based on computer simulation with taking into account the SOD, phase mismatching, selfand cross-modulation for interacting waves.
