1943nm Fiber Brag Grating UFBG
The Fiber Brag Gratings (FBGs) can be FBG mirrors which are based on the reflective properties of the FBGs written in the core of an optical fiber waveguide. The FBGs’ principal application is to use a high and low reflector to form a stable laser cavity having the lasing wavelength selected by the low reflector. Lightcomm FBGs have been customized to address the specific requirements of high efficiency and low noise laser applications.
