建立了467 nm半导体激光器系统，用于驱动{sup 171}Yb{sup +}中{sup 2}S{sub 1/2{yields}}{sup 2}F{sub 7/2}电八极跃迁。激光器的频率稳定在由超低膨胀玻璃制成的参考腔中，并被证明在1 s时具有优于2x 10 {sup -15}的相对不稳定性，并且在几个小时内具有稳定的线性漂移率，变化低于10 mHz/s。该系统被应用于单囚禁激光冷却的{sup 171}Yb{sup +}离子的光谱。我们得到的八极跃迁的激发光谱的共振激发概率约为65%，基本上傅立叶变换限制的分辨率为13 Hz。
A diode-laser system at 467 nm is built in order to drive the {sup 2}S{sub 1/2{yields}}{sup 2}F{sub 7/2} electric octupole transition at 467 nm in {sup 171}Yb{sup +}. The frequency of the laser is stabilized to a reference cavity made of ultra low expansion glass and is demonstrated to have a relative instability of better than 2x10{sup -15} at 1 s and a stable linear drift rate with variations below 10 mHz/s over several hours. The system is applied for spectroscopy of a single trapped laser-cooled {sup 171}Yb{sup +} ion. We obtain excitation spectra of the octupole transition with a resonant excitation probability of about 65% and an essentially Fourier transform-limited resolution of 13 Hz.
