We investigate the role of competing nonlinear responses in the formation and propagation of bright spatial solitons. We use nematic liquid crystals (NLCs) exhibiting both thermo-optic and reorientational nonlinearities with continuous-wave beams. In a suitably prepared dye-doped sample and dual beam collinear geometry, thermal heating in the visible affects reorientational self-focusing in the near infrared, altering light propagation and self-trapping.
我们研究了竞争非线性响应在亮空间孤子形成和传播中的作用。我们使用了向列型液晶（NLC），其在连续波光束作用下同时表现出热光非线性和重取向非线性。在一个经过适当制备的染料掺杂样品和双光束共线几何结构中，可见光中的热加热会影响近红外光中的重取向自聚焦，从而改变光的传播和自陷。
