The Cotton-Mouton (Voigt) and Faraday effects induce adjustable linear and circular birefringence in optical media with external magnetic fields. We consider these effects as a technique for magneto-optical control of the transmission of bimodal light beams through Kerr-nonlinear crystals. Numerical analysis suggests that a properly applied magnetic field may accelerate, delay, or arrest the collapse of (2+1)D beams. Experimentally, the magnetic collapse acceleration is demonstrated in a bulk yttrium iron garnet (YIG) crystal.
科顿-穆顿（沃伊特）效应和法拉第效应在存在外部磁场的光学介质中会产生可调节的线性和圆双折射。我们将这些效应视为一种用于磁光控制双峰光束通过克尔非线性晶体传输的技术。数值分析表明，适当施加磁场可能会加速、延迟或阻止（2+1）维光束的坍缩。在实验中，在块状钇铁石榴石（YIG）晶体中证明了磁坍缩加速现象。
