Fiber Bragg Grating for Fiber Laser
FBG(Fiber Bragg Grating) is periodic refractive 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.
Low temperature slope is less than 0.01 ℃ /W under 915 nm pump power
Central wavelength 106onm~1080nm,1940nm optional
Bandwidth operational 0.1nm - 4nm
Wavelength mismatch within 0.2nm
Fiber type can be customized
