    With the rapid development of high power laser and optical communication technology, how to eliminate the reflected noise generated inside the optical system is a crucial challenge. The magneto-optical isolators are magnetically active devices designed according to the Faraday effect, which can effectively isolate most of the reflected light to ensure the stable operation of the optical system. As the core component of the magneto-optical isolator, research and application of Faraday magneto-optical materials are promoting the update and development of the magneto-optical isolators. CeF3 crystals have the advantages of high transmittance, wide transmission range and high Verdet constant, and have received widespread attention in recent years for the excellent magneto-optical property. But its traditional growth methods have some disadvantages such as high cost and long cycle. In this study, multiple CeF3 crystals were successfully obtained by the porous crucible technology through optimizing the temperature field structure and process of Bridgman growth technology. Compared with commercial TGG(Tb3Ga5O12) crystals, CeF3 crystals have a significantly high transmittance up to 92%, and a comparable Verdet constant in the near-infrared wavelength, and the thermal performance test results show that CeF3 crystals have high specific heat, indicating a strong thermal shock resistance and a high laser damage resistance. Therefore, the porous crucible technology is a large-scale and low-cost production method, which can be used to grow CeF3 crystals achieving with excellent physical properties, exhibits great potential to develop magneto-optical isolators in the near-infrared band.
