The 3 Ports 1064nm High Power Polarization Maintaining Optical Circulator is a precision-engineered, non-reciprocal passive optical device that routes light sequentially from Port 1 → Port 2 and Port 2 → Port 3, while maintaining the polarization state of the transmitted light with excellent stability. Operating at 1064 nm, this circulator is specifically designed for Yb-doped fiber laser systems, amplifiers, and nonlinear optical setups, offering superior performance in high-power and polarization-sensitive environments.
