我们报告了 790 nm 至 980 nm 高功率、高亮度单发射激光二极管的开发不断取得的进展，以便在工业和泵浦应用中可靠使用。 nLIGHT 的二极管激光器技术在此光谱范围内展现了高性能，相应的峰值电光功率转换效率约为 65%。这些泵已集成到 nLIGHT 的光纤耦合泵模块 elementTM 中。我们报告芯片和光纤耦合模块的性能和可靠性的最新更新。本文还包括一种新的芯片设计，其慢轴发散度显着缩小，从而进一步提高了可靠的功率和亮度。这些设备的初步可靠性评估数据也将在此提供。
We report on continued progress in the development of high power and high brightness single emitter laser diodes from 790 nm to 980 nm for reliable use in industrial and pumping applications. High performance has been demonstrated in nLIGHT’s diode laser technology in this spectral range with corresponding peak electrical-to-optical power conversion efficiency of ~65%. These pumps have been incorporated into nLIGHT’s fiber-coupled pump module, elementTM. We report the latest updates on performance and reliability of chips and fiber-coupled modules. This paper also includes a new chip design with significantly narrower slow-axis divergence which enables further improved reliable power and brightness. Preliminary reliability assessment data for these devices will be presented here as well.
