钠原子谱线激光光源不仅在光谱学研究中有广泛的应用 ,而且在军事应用方面 (如空间目标监测与识别 )有着重要应用。半导体抽运的固体激光器产生钠黄光具有效率高、体积小、光束质量好等优点 ,美、德、法、英等国开展了大量的研究 ,而我国尚未开展全固态钠信标光源研究。本实验 Sodium atomic spectral line laser light source not only has a wide range of applications in spectroscopy, but also has important applications in military applications (such as space target monitoring and recognition). Solid-state lasers produced by semiconductor pumps produce sodium-yellow light with high efficiency, small volume and good beam quality. Many studies have been carried out in the United States, Germany, France and Britain. However, the research on all-solid sodium beacon light source has not been carried out in our country. this experiment
