| 摘 要： | It is numerically proven that dissipative holographic solitons, which are proposed for biased photorefractive materials when the self-trapping beam couples coherently with a pump beam via two-wave mixing, can exist when the intensity of the self-trapping beam is comparable with or stronger than that of the pump beam. Based on the mechanism of forming the soliton, an approach is established used to find the numerical solutions of the soliton. Such numerical solutions have been found for a broad range of system parameters. An experimental way to find such solitons is proposed.
