英文摘要	In this letter, a sapphire fiber Bragg grating (SFBG) is fabricated by a femtosecond laser line-by-line scanning method. A third-order fiber Bragg grating is obtained in a single crystal sapphire fiber with a diameter of 60 mu m. Compared to the SFBG written by a point-by-point method, the SFBG written by the line-by-line method has a higher reflectivity and grating with about 15% reflectivity is achieved when the track length is about 40 mu m. The temperature sensing characteristics of this SFBG from a room temperature to 1600 degrees C are studied, and the temperature sensitivity of SFBG is 34.96 pm/degrees C from 1000 degrees C to 1600 degrees C. The strain characteristics are also tested at the temperature of 26 degrees C, 500 degrees C, 1000 degrees C, and 1600 degrees C, and the strain sensitivities are 1.42, 1.42, 1.44, and 1.45 pm/mu epsilon, respectively. These characteristics show that this SFBG has potential applications in a harsh environment structural health monitoring.
