The main works and results we have accomplished are as follows : 1 ) red - detuned locking of cooling / trapping laser to the cycling transition of cesium cooling has been accomplished by means of a double - passed acoustic - optical frequency shifting system and the technique of saturated absorption spectroscopy . the short - term residual frequency jitter is less than 350khz ; 2 ) automatic controlling system by computer programs has been established for laser cooling and trapping and cavity qed experiment . the laser and magnetic fields can be controlled by the acoustic - optical modulator and the electronic - controlled logic gate respectively 具体如下: 1 )采用了往返两次通过的声光频移系统结合饱和吸收光谱技术的实验方案,实现了冷却俘获激光频率相对于铯原子冷却循环跃迁的负失谐锁定,短期频率稳定度约在350khz以内,并可方便地调节其负失谐量而无须对后续光路再作调整; 2 )建立了一套基于计算机程序控制的、铯原子激光冷却与俘获实验所需的时序控制系统。
