摘要：

This Letter presents distributed Bragg reflector (DBR) fiber lasers for high-temperature operation at 750 degrees C. Thermally regenerated fiber gratings were used as the feedback elements to construct an erbium-doped DBR fiber laser. The output power of the fiber laser can reach 1 mW at all operating temperatures. The output power fluctuation tested at 750 degrees C was 1.06% over a period of 7 hours. The thermal regeneration grating fabrication process opens new possibilities to design and to implement fiber laser sensors for extreme environments. (C) 2013 Optical Society of America
