| 摘 要： | 对文献1]中所报道的LiNbO3:Fe晶体从自散焦到自聚焦动态转换的过程,在实验和理论上作了进一步研究.以实验结果为依据,提出了相位共轭共振腔的理论模型,分析了该共振腔在从自散焦到自聚焦的动态转换过程中所起的作用,并提出了一种新型的亮空间孤子,即相位共轭亮空间孤子,指出相位共轭亮空间孤子是相位共轭共振腔中的一个模

| Abstract: | We have further studied experimentally and theoretically the process of conversion from self-defocusing to self focusing in LiNbO 3:Fe crystals, which was reported in Acta Phys.Sin. 50 483. Based on our experimental result, we have proposed a new type of theoretical model of phase conjugate resonant cavity, analyzed the role of the cavity in the process of conversion from self defocusing to self focusing. We have also proposed a new type of bright spatial soliton, i.e.,the phase conjugate bright spatial soliton, and indicated that the bright spatial soliton is a mode in the phase conjugate resonate cavity. |
