1064nm 2W PM Faraday Isolator

Overview

The FT-1064-16 is a polarization-maintaining optical isolator built around Faraday rotation and rated for average optical power up to 2 W at a 1064 nm center wavelength. It blocks reflected light from traveling back toward the laser source, protecting seed diodes and amplifiers in high-power fiber laser chains. Single-stage and dual-stage versions cover different isolation budgets: typical peak isolation reaches 35 dB for the single stage and 50 dB for the dual stage at 23 °C. Insertion loss is rated at four input power levels up to 2 W. Minimum return loss is 45 dB with a 20 dB minimum extinction ratio, and nanosecond pulses up to 10 kW peak power are supported.
