利用衍射光栅的光反馈实现了室温下690 nm可见光半导体激光器的稳频。通过记录锶的689 nm互组合线的亚多普勒信号和解析碘的近P63 R70（8，4）跃迁的超精细结构，证明了这些激光器提供高分辨率光谱的可能性。
A visible diode laser emitting at 690 nm at room temperature has been frequency-stabilized using a simple scheme based on optical feedback from a diffraction grating. The possibilities offered by these lasers for high-resolution spectroscopy are demonstrated by recording the sub-Doppler signal of the 689 nm intercombination line of strontium and resolving the hyperfine structure of the close P63 R70 (8, 4) transitions of iodine.
