3 Ports 1064nm High Power Polarization Maintaining Optical Circulator

3 Ports 1064nm High Power Polarization Maintaining Optical Circulator

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.

Built with PLMA-GDF-10/125-M fiber, the circulator ensures precise polarization alignment, with the slow axis aligned to the key (default). It features low insertion loss, high isolation, high return loss, and a high polarization extinction ratio (PER), delivering outstanding reliability under both continuous-wave (CW) and pulsed laser operation. The device’s optical components are coated with high damage-threshold films to ensure stable performance under powers up to 100 W CW and 20 kW peak @ ns pulse.

Its compact, rugged construction and excellent thermal management make it ideal for integration into fiber laser systems, ultrafast amplifiers, interferometers, and other high-precision optical instruments where polarization control and high power handling are critical.
