High power free space isolator 980/1030/1064/1080/1150/1310/1550/2000nm

A high-power infrared isolator is a unidirectional device used to protect a light source from possible back reflections or signals in an optical system. Reverse reflection can damage the laser source or cause mode hopping, amplitude modulation, or frequency shift. In high-power applications, reverse reflection can cause instability and power peaks, and even damage the light source. Our high-power isolator is a passive magneto-optical device that preferentially transmits light in a single direction and shields upstream optical devices from reverse reflection. The operation of the isolator is based on the Faraday effect.
