To meet the needs of customers for the use of infrared bands,EOTDeveloped a new generation of infrared isolators, including near-infrared~Mid infrared, with low-power models and fiber Faraday isolators, etc.
EOT's1050~1080 nmLow power infrared Faraday isolators can be used with dichroic glass polarizers or polarizing beam splitters cubes. To protect the seed source fromQThe back reflection of the switch laser,EOTIt is recommended to use polarizing beam splitter cubes as they can withstand high pulse energy. if needed60 dBTo ensure that backward reflection does not cause frequency instability of a single frequency single seed laser, two isolators can be used in series.

EOT'sMESOSInfrared isolators have 30 Years of successful experience have done a great job in protecting lasers from unstable and potentially destructive back reflections.
EOT'sMESOSThe rotator and isolator provide the industry's best reliability, while offering excellent isolation and maintaining very high transmission.EOTThe infrared isolator rotates the linearly polarized light plane forward and additionally in the reverse direction using the Faraday effect from high Wied constant, low absorption materials 45Non reciprocal rotation of degrees. When these Faraday rotators are placed between cross polarizers, they can be used as Faraday isolators. This can be used in many aspects, such as mapping, LiDAR, medical and biological sciences, chirp pulse amplification(CPA)Environmental sensing, spectroscopy, medical systems, research, and equipment manufacturing, among others.
