标题： Magnetooptical control of light collapse in bulk Kerr media

摘要： 磁光晶体可以通过Cotton-Mouton效应和法拉第效应高效地控制光的双折射。 这些效应使得可调线性双折射和圆双折射能够独特地结合，从而影响非线性Kerr介质中光的传播。 我们通过数值模拟表明，结合的双折射可以加速、延迟或阻止(2+1)D光束的非线性坍缩，并报告了在外部磁场下块状钇铁石榴石(YIG)晶体中坍缩开始加速的实验观察结果。 显示英文摘要

摘要： Magneto-optical crystals allow an efficient control of the birefringence of light via the Cotton-Mouton and Faraday effects. These effects enable a unique combination of adjustable linear and circular birefringence, which, in turn, can affect the propagation of light in nonlinear Kerr media. We show numerically that the combined birefringences can accelerate, delay, or arrest the nonlinear collapse of (2+1)D beams, and report an experimental observation of the acceleration of the onset of collapse in a bulk Yttrium Iron Garnet (YIG) crystal in an external magnetic field.
