Abstract:

The evolutional rules of parameters and critical powers of transmission of orthogonal polarization center-coincidence double Hermite-Gaussian beams are calculated with variational approximation method in strongly nonlocal medium with exponential-decay response. The Hermite-Gaussian spatial optical solitons are obtained when the two beams are incident with critical powers; The beams can form breathers when the two beams are incident with total critical power but two incident powers are different. By the research of numerical simulation, the beam of low order can get approximation soliton solution;while the order of beam is more than three,the soliton solution can’t be get. When comparing the variational solution with numerical solution, result shows that when the order of beam is under the third, variational solution can reflect the propagation properties of orthogonal polarization center-coincidence double Hermite-Gaussian well in strongly nonlocal medium with exponential-decay response.
