Propagation and collision of photorefractive screening solitons Conference Paper uri icon


  • The characteristic features of photorefractive solitons as well as their interactions were studied in strontium niobate crystal. A single beam propagating through the crystal formed a soliton while two beams simultaneously launched formed solitons that strongly interacted when collided. The beam interactions resulted in energy transfer between the solitons which could be changed by varying a relative phase of the two solitons. To avoid direct energy transfer because of two-wave mixing, the interaction geometry was arranged in a way so both beams can propagate in the vertical plane. By completely suppressing the photorefractive wave mixing, formation of additional solitons was observed.
