Product details
Overview
Operating at 1040 nm, this PM isolator is built for 300 mW continuous-wave service and preserves the input polarization state. Incoming light passes forward while reverse feedback is strongly attenuated, keeping pump diodes and oscillator stages safe from reflections that cause noise or damage. The optical behavior is defined by low insertion loss, high return loss, high isolation and a strong extinction ratio, which maintains polarization purity in coherent links and ultra-fast laser sources. It is intended for ultra-fast fiber lasers, fiber sensors and measurement instruments where a stable polarization axis is essential. The in-line housing with PM pigtails drops directly into polarization-maintaining assemblies.
