This Letter presents distributed Bragg reflector (DBR) fiber lasers for high-temperature operation at 750°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°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.
这封信件介绍了分布式布拉格反射器（DBR）光纤激光器，其可在 750°C 的高温下运行。热再生光纤光栅被用作反馈元件来构建掺铒 DBR 光纤激光器。在所有工作温度下，光纤激光器的输出功率可达 1mW。在 750°C 下测试的输出功率波动在 7 小时内为 1.06%。热再生光栅制造工艺为设计和实现用于极端环境的光纤激光传感器开辟了新的可能性。
