Fiber Bragg Grating
FBG (Fiber Brag Grating) is a periodic reflective index modulation in optical fiber core through UV exposure which can achieve the modulation of signal light in optical fiber. It is an indispensable part of a high power fiber laser.
Sets of High Reflectors (HR) and Output Couplers (OC) are available for desired wavelength based on 10/130, 14/250 or 20/400 fibers. We could write FBG on other fiber geometries as per customer demand. High power versions with capability of handling 4000W available.
Features:
- Low temperature slope in less than 0.01C/W under 915nm pump power
- Central wavelength 1060nm-1090nm
- Bandwidth operational 0.1nm-4nm
- Wavelength mismatch within 0.2nm
- Fiber type can be customized
Application:
- Fiber lasers
- Strain sensing
