Product Description

1650nm Monodirectional LC APC FBG Optical Reflector Filter, Green Housing


Fiber Laser Gratings are typically produced using double-clad fiber. They are generally used in pairs, including a high reflectance grating (Greater than 99.9%) and a low reflectance grating (10-20%), with a gain fiber between the two fiber gratings. The pump light propagates between the core and the inner cladding and the seed light propagates only in the core. The seed light is amplified by the grating for multiple oscillations, and output from the low reflectance fiber grating direction. The double-clad fiber for making 1060nm fiber laser grating is a single-mode fiber, which can ensure good beam quality and pump efficiency, generally up to tens of watts or even hundreds of watts.


Keyed Characteristics

(1) High Stability and Reliability.
(2) Low Coupling Loss and Compact Size.
(3) Less Heat, Faster Heat Dissipation.
(4) High Beam Quality.
(5) Compliant with Telcordia GR-1221-CORE.
(6) Compliant with RoHS.
