染料激光器使光谱学进入一个新的时代。它的可调谐性对基本的精密测量(如氢原子光谱术)以及对光频标的新的量子系统的研究是有重要意义的。在上述研究中,连续染料激光比脉冲染料激光好,因为虽然技术上麻烦些,但前者有窄的光谱宽度以及振幅和频率的超稳定性。但是用连续染 Dye lasers have brought spectroscopy to a new era. Its tunability is important for basic precision measurements such as hydrogen atomic spectroscopy and for the study of new quantum systems for optical frequency standards. In the above studies, continuous dye lasers are better than pulsed dye lasers because, although technically troublesome, the former has a narrow spectral width and an ultra-stable amplitude and frequency. But with a continuous dye
