1064nm PM High Power Three-Port Optical Circulator

Overview

Where polarization must survive the round trip, the FT-1064-12 keeps the 1064 nm circulator path polarization-maintaining end to end. Light into port 1 leaves through port 2, and light arriving at port 2 is redirected to port 3, so a PM amplifier forwards its output while back-reflections are diverted from the seed. PM versions hold a minimum 20 dB extinction ratio at 23 °C, keeping polarization-dependent performance predictable in fiber lasers and sensing chains. Peak isolation is 25 dB typical with 1.3 dB insertion loss (1.5 dB maximum). Average power handling spans 0.3–20 W with 10 kW peaks for nanosecond pulses. Pigtail choices include PM980, Hi1060, PM1060L and PLMA-GDF-10/125-M, in a 70x28x26 mm package operating from +10 to +50 °C.
