Research progress and applications of fluoride magneto-optical crystals
With the rapid development of optical communication technology and the improvement of laser average power,magneto-optical isolators are required to ensure the unidirectional propagation of light,thereby maintaining the stable and efficient operation of the optical system.As the core component of optical isolators,magneto-optical medium has also developed rapidly.Several magneto-optical materials and the shortcomings of the current magneto-optic garnet crystals,as well as the principle and application of the Faraday effect are first briefly introduced.Then,the advantages and disadvantages of the current various fluoride magneto-optical crystals as a new generation of magneto-optical crystals are systematically analyzed.Finally,the potential application of CeF3 magneto-optical crystals and the future development of fluoride magneto-optical crystals are prospected.
