Fiber Bragg Grating (FBG) is the periodic refractive-index structure in an optical fiber core, where the light of a specific wavelength is reflected. It can be used as temperature or a distorted sensor by measuring change of the reflective wavelength of FBG. We processed FBG using a Chirped Pulse Amplification titanium sapphire laser. As a result, we confirmed produced FBG had the tolerance at the high temperature. The heat-resistant FBG sensor developed using ultra-short pulse laser processing will contribute to the surveillance of power plants.
