SodiumStar系统是一种专为地面望远镜中自适应光学控制而设计的高功率“导星”激光器。 该系统基于红外DFB二极管激光器与后级拉曼光纤放大器的谐振倍频，可在钠离子的波长589nm处提供20瓦以上输出功率，同时保证低于5兆赫的光谱宽度。 DL RFA SHG pro是经过调整的亚MHz线宽版本，具有中等功率（2 W），可用于激光冷却实验。
在智利Paranal的超大口径望远镜（VLT）上用于自适应光学系统的导星激光器： 激光操作面临高度，抗震设计和重力不变操作的挑战， TOPTICA的导星激光器在589 nm处提供22 W的稳定输出功率。
SodiumStar系统及其研发团队已获得由Berthold Leibinger基金会颁发的2016年激光研究创新奖和美国光学学会授予的2017年Paul F. Forman团队工程设计卓越奖。
