Method for setting heating condition, method for manufacturing fiber bragg grating, and method for manufacturing fiber laser system

Abstract

A method for setting a heating condition for thermal aging of each of fiber Bragg gratings, includes: determining, based on a correspondence γ(Ed) between a temperature coefficient γ of each of the fiber Bragg gratings and a demarcation energy Ed of each of the fiber Bragg gratings, a first lower limit Edmin of the demarcation energy Ed such that the temperature coefficient γ is not more than a desired upper limit γmax; and setting the heating condition for thermal aging of each of the fiber Bragg gratings such that the demarcation energy Ed is not less than the first lower limit Edmin.
