%X 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.
