黄光波段的激光器在激光表演、激光钠导星、玻色爱因斯坦凝聚、激光化学、原子冷却与捕获、激光生物效应、激光医学等方面都具有重要的应用。尤其在眼科诊断和治疗方面,相比其他波长的激光,577±5nm波段的黄色激光为眼科光凝疗法最佳光谱选择区域。近年来,黄光激光器已成为激光领域的研究热点,科研人员一直不断探索实现黄光激光的方法及其相关技术的应用,其中新型激光介质的开发成为一个重要途径。2016年6月,本课题组通过半导体激光抽运Dy∶YAG增益介质的方法,采用Dy∶YAG单晶(中科院 The laser in the yellow band plays an important role in laser show, laser sodium guide, Bose Einstein condensate, laser chemistry, atomic cooling and capture, laser biological effect, laser medicine and so on. Especially in ophthalmologic diagnosis and treatment, the yellow laser in 577 ± 5 nm band is the best spectral selection area for ophthalmic photocoagulation compared to other wavelengths. In recent years, the yellow laser has become a hot research field in laser field. Researchers have been continuously exploring the application of the method of yellow laser and its related technologies. The development of new laser medium has become an important approach. In June 2016, our group adopted the laser pumping Dy: YAG gain medium method, using Dy: YAG single crystal (Chinese Academy of Sciences
