We demonstrated a high-power and highly efficient Pr-doped waterproof fluoride glass fiber laser at 522.2 nm excited by two-polarization-combined GaN laser diodes and achieved a subwatt output power of 598 mW and slope efficiency of 43.0%. This system will enable us to make a vivid laser display, a photocoagulation laser for eye surgery, a color confocal scanning laser microscope, and an effective laser for material processing. Direct visible ultrashort pulse generation is also expected.
我们展示了一种由双偏振组合 GaN 激光二极管激发的高功率、高效率掺镨防水氟化物玻璃光纤激光器，在 522.2nm 波长下获得了 598mW 的亚瓦级输出功率和 43.0%的斜率效率。该系统将使我们能够实现生动的激光显示、眼科手术的光凝激光、彩色共焦扫描激光显微镜以及有效的材料加工激光。预计还可以直接产生可见光超短脉冲。
