摘要: In the past decade spatial solitary waves in materials exhibiting non-Kerr nonlinearities have attracted a lot of attention. The dynamics solitons quadratic media was investigated both theoretically and experimentally [1, 2, 3]. Solitons photorefractive crystals also been observed [4, 5, 6, 7, 8]. this paper, optical nonlinearity are investigated. These two completely different origin but as shown, recent, pioneering paper [9], they can influence propagation beam light (it is shown that efficiency second harmonic generation increases due to creation channel). Here we show relatively weak second- wave, guide powerful fundamental wave.
