1064nm High Power Dual-stage Fiber Optic Isolator 1-20W
product description
Fiber optic isolators primarily use the Faraday effect of magneto-optical crystals to isolate reflected light, allowing passive magneto-optical devices that transmit light in a single direction. Fiber optic isolators are used to protect the source from adverse effects caused by back reflections or signals; back reflections can damage the laser or cause mode hopping, amplitude variations, or frequency shifts. In high power applications, back reflection can also cause instability and power spikes.
The isolators produced by Mingchuang Optoelectronics have high isolation, low insertion loss and high withstand power. The different wavelength, power and fiber isolators can be customized according to user needs. The products are widely used in fiber lasers, fiber amplifiers, laser communication, fiber transmission. Sense, scientific research, and other fields.
