近年来，589 nm激光器在激光钠导星、激光雷达、自适应光学等领域备受关注。因此，589 nm 的钠导星技术尤其受到关注。钠导星技术要求连续波黄光激光器的平均功率为瓦特级，线宽窄，能够精确调谐以匹配过渡线。根据产生方式，钠导星激光器可分为染料激光器、固体激光器、光泵浦半导体激光器和光纤激光器四种类型。固体激光器包括和频产生、受激拉曼散射和光参量放大器。其中，使用最多的是和频发生激光器。阐述了它们的发展历史和研究现状，为该领域今后的研究提供了有益的参考。
In recent years, 589 nm lasers have attracted much attention in the fields of laser sodium guide star, laser radar, and adaptive optics. Therefore, the sodium guide star technology at 589 nm has been particularly topical. The sodium guide star technology requires that the average power should be Watt-level for the continuous-wave yellow laser which having narrow-linewidth and are capable of being tuned to match transition lines accurately. According to the generation method, the sodium guided star laser can be divided into four types: dye lasers, solid-state lasers, optically pumped semiconductor lasers, and fiber lasers. Solid-state laser includes sum-frequency generation, stimulated Raman scattering and optical parametric amplifier. Among them, sum-frequency generation lasers are used mostly. The development history and state of the art of them are expatiated, which is useful reference for the future research in this field.
