We report on the experimental observation of a dynamic instability in the interaction of counterpropagating self-trapped beams in a photorefractive strontium barium niobate crystal. While the interaction of copropagating spatial optical solitons exhibits only transient dynamics, resulting in a final steady state, the counterpropagating geometry supports a dynamic instability mediated by intrinsic feedback. Experimental observations are compared with and found to be in qualitative agreement with numerical simulations.

  14. It should be noted that the threshold parameter is actually the coupling strength, which is the interaction length times the PR coupling constant. Holding the latter at a fixed value, we restricted the investigation to the interaction length threshold.
