摘要

我们通过数值建模，在非线性放大和吸收快速响应介质的准光学近似（抛物线方程）框架内发现了一类新的三维矢量激光孤子。这些孤子具有不同的偏振奇异性。研究了孤子稳定的参数范围，并指出了离开这一范围后的失稳情况。

Toroidal Vector Dissipative Optical Solitons with Polarization Singularities

We have found a new class of three-dimensional vector laser solitons within the framework of the quasi-optical approximation (parabolic equation) for a medium with a fast response of nonlinear amplification and absorption by numerical modeling. These solitons have different polarization singularities. The range of parameters in which solitons are stable is studied, and scenarios of destabilization when leaving this range are indicated.
