980nm fiber grating locker


The wavelength-locked fiber grating can effectively improve the output power of the light source and the accuracy and reliability of the output light wavelength, reduce the spectral mode jump of the pump laser, and reduce the optical power fluctuation caused by temperature changes and drive current changes, so improve pump laser performance. The wavelength lockers are suitable for laser diodes of 980nm and 1480nm wavelengths. Depending on the pump laser locking requirements, the wavelength-locked grating can be either single-grating or dual-grating.
