High-Power Polarization-Maintaining Isolator 1064nm 2W

Name: High Power Polarization Maintaining Isolator 1064nm 2W
Brand: 熵光

The High-Power PM Isolator is a high-performance optical isolation device designed for the 1064nm band, supporting up to 2W CW power handling. Available in single-stage and dual-stage configurations with P-grade and A-grade options. Dual-stage P-grade: typical insertion loss 2.4dB,, peak isolation 55 dB; single-stage P-grade: typical insertion loss 1.5dB,, peak isolation 40 dB. Features high extinction ratio (B-type ≥20 dB, F-type ≥22dB),), high return loss (≥50dB).). Built with PM Panda fiber design for stable polarization state transmission. Compliant with Telcordia GR-1209-CORE and GR-1221-CORE standards and RoHS certified. Widely used in ultrafast laser systems, high-power fiber lasers, fiber amplifiers, laser processing, and polarization-maintaining optical systems.
