论文摘要
随着对中红外光谱区域的兴趣日益增长，最近已重新审视了有效的高性能红外源开发的肿瘤障碍。尽管历史上比其他稀土离子受到的关注较少，但近年来，用作为激光材料作为激光材料的激光器已经建立了创纪录的中红外性能，包括可调性从2.8到3.4 um（除了4.3 um激光外），超过10 W的连续波动功率，超过10 W，大于73％的SLOPE效率，甚至超过73％的效率。在此，检查了肾上腺离子的独特能量水平结构和光谱，并对导致这种兴趣的重新兴起和随后创纪录的中红外激光性能进行了研究。除了调查未来的许多机会外，还强调了新兴肿份激光器的中红外应用。
With growing interest in the mid-infrared spectral region, dysprosium has recently been revisited for efficient high-performance infrared source development. Despite historically receiving less attention than other rare earth ions, in recent years lasers utilizing the dysprosium ion as the laser material have set record mid-infrared performance, including tunability from 2.8 to 3.4 um (in addition to 4.3 um lasing), continuous wave powers exceeding 10 W, greater than 73% slope efficiencies, and even ultrafast pulsed operation. Herein, the unique energy level structure and spectroscopy of the dysprosium ion are examined and the major developments that have led to this resurgence of interest and subsequent record mid-infrared laser performance are surveyed. Also mid-infrared applications of emerging dysprosium lasers are highlighted, in addition to surveying the many opportunities that lie ahead.
