1064nm 300mW PM Faraday Isolator

Overview

For PM paths that cannot tolerate polarization drift, the FT-1064-18 protects 1064 nm sources at up to 300 mW continuous. Choose both-axis operation for a 20 dB minimum extinction ratio, or fast-axis-blocked for 22 dB, matching the polarization layout of the host system. Isolation is 35 dB typical peak in the single stage and 52 dB in the dual stage at 23 °C, with 1.5 dB and 2.4 dB typical insertion loss respectively, so even the compact single stage gives meaningful feedback suppression in MOPA seeds. Return loss stays at 50 dB minimum on both ports. The φ5.5x35 mm PM panda-fiber package operates from -5 to +50 °C and suits fiber laser chains and test instruments.
