PM 980nm High-Power Optical Isolator (TGG Based)
This PM 980nm High Power Optical Isolator, based on TGG crystal technology, delivers high isolation, low insertion loss, and excellent optical performance for demanding high-power applications. Operating at the 980±5 nm wavelength, it provides reliable polarization maintenance through slow-axis operation with fast-axis cutoff, supporting power handling capabilities from 1W to 100W.
Ideal for MOPA fiber lasers, PM fiber amplifiers, and high-power fiber laser systems, the isolator ensures stable performance across its specified temperature range. Its robust construction and high extinction ratio make it suitable for precision environments including CATV links and optical test systems. Custom configurations including fiber type, connector style, and fiber length are available to meet specific integration requirements.
