The 3 Ports 1030nm High Power Polarization Maintaining Optical Circulator is a precision-engineered, non-reciprocal passive optical device designed to direct light sequentially from Port 1 → Port 2 and Port 2 → Port 3, while maintaining the polarization state of the transmitted light with high stability. Operating at 1030 nm, it is optimized for Yb-doped fiber laser systems, ultrafast amplifiers, and high-power optical setups, providing exceptional optical isolation, low insertion loss, and excellent polarization extinction ratio (PER).
