摘要

由于当前国内980 nm半导体泵浦激光器设计经验及生产工艺的缺乏，高功率980 nm半导体泵浦激光器核心技术一直无法突破，文章采用国产化解决方案，包括芯片、光栅和耦合光纤等设计与实现，通过应用楔形光纤直接耦合的全金属化封装，选择双光栅结构进行波长锁定，实现了－50～75 ℃工作温度范围内，输出光功率达400 mW的980 nm半导体泵浦激光器的研制，其波长稳定性可达0.01 nm/℃。并且通过了5 000 h以上、工作电流800 mA和环境温度75 ℃的带电老炼测试，为满足高可靠性的国产化泵浦激光器奠定了基础。

Abstract

Due to the lack of domestic 980 nm pump laser design experience and production process

the key technology of high power 980 nm pumped laser to break through. In this paper

a 980 nm pump laser with 400 mW output power has been successfully developed by using a domestic solution

including the design and implementation of chips

gratings and coupling fibers. By using the all metallized package directly coupled with wedge-shaped fiber and selecting the double grating structure for wavelength locking

the wavelength stability of the 980 nm pumped laser with 400 mW output power in the operating temperature range of -50~75 ℃ can reach 0.01 nm/ ℃. Moreover the 980 nm pump laser has passed the 800 mA charge aging at 75 ℃ for more than 5 000 h. This has laid a foundation for the research of domestic pump lasers with high reliability.
