| 摘 要： | 对于单纵模半导体激光器（ＬＤ），应用往返两次通过一个声光频移系统的方法，结合铯原子饱和吸收稳频技术，实现了激光频率相对于铯原子Ｄ２线６２Ｓ１／２（Ｆ＝４）→６２Ｐ３／２（Ｆ′＝５）超精细跃迁的偏频锁定。其特点是可通过调谐声光频移系统的工作频率方便地改变偏频量，而不需要对光路进行再调整

| Abstract: | Letting the beam doubly pass an acousto optic frequency shifting system and using the technique of saturated absorption spectra of cesium atoms we realized the frequency offset locking of a single longitudinal mode laser diode to the hyperfine transition of 6 2S 1/2 F=4→6 2P 3/2 F′=5 of cesium atoms. The characteristic is that the detuning can be changed conveniently by tuning the working frequency of the acousto optic frequency shifter without readjusting the optical system. |
