摘要:
当前，光纤激光器工作温度范围一般较窄，如果能够扩展激光器的工作温度范围，则有望在更多的环境和领域得到应用。近期，国防科技大学基于风冷结构的光纤耦合半导体激光器（LD）泵浦的全光纤振荡器方案，在−50～50 ℃超宽温范围内实现了1 kW量级的激光输出。通过优化系统设计，有望进一步提升宽温运行激光器的输出功率。

Abstract:
At present, the operating temperature range of fiber lasers is generally narrow, and if the operating temperature range of lasers can be extended, they are expected to be applied in more environments and fields. Recently, the all-fiber oscillator scheme pumped by an air-cooled fiber coupled semiconductor laser (LD) at the National University of Defense Technology has achieved a laser output of 1 kW in the ultra-wide temperature range of −50～50 ℃. By optimizing the system design, the output power of the laser with wide temperature operation is expected to be further improved.
