Bragg grating FBG

FBG(Fibre Bragg Grating) produced by YOFC is a periodic refractive index modulation in optical fibre core through UV exposure which can achieve the modulation of signal light in optical fibre. It is an indispensable part of a high power fibre laser. High power fibre laser Low Temperature Slope is less than 0.015℃ /W under 915 nm pump power Central wavelength 1064nm or 1080nm Bandwidth operational 0.1nm~3.2nm Wavelength mismatch within 0.2nm Fibre type can be customized
