摘　　要：光通信技术发展迅速,激光平均功率不断提高,磁光隔离器是保证激光单向传输、维持光学系统稳定高效工作的基础,而磁光介质作为磁光隔离器的核心部件也因此得以快速发展。首先简要介绍了几种磁光材料以及当前广泛应用的石榴石磁光晶体的缺点、法拉第效应的原理和应用,随后系统分析了作为新一代磁光晶体的各类氟化物磁光晶体的优缺点,最后展望了CeF_(3)磁光晶体潜在的应用前景以及未来氟化物磁光晶体的发展趋势。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 CeF_(3) magneto-optical crystals and the future development of fluoride magneto-optical crystals are prospected.
