用饱和吸收光谱法对二极管激光器进行了稳频,使得激光 器的等效线宽小于1~MHz,并利用声光调制器使激光的频移量得到 控制,能满足激光冷却与囚禁原子对激光频率稳定性和频移量的要 求,实现了Rb原子的激光囚禁。

Frequency of diode laser is stabilized by using saturated absorption spectroscopy, the linewidth of laser frequency is less than 1 MHz, and the offset of laser frequency can be controlled by using acousto-optical modulator. It satisfied the requirement of laser cooling and trapping of atoms, and thus has been used to the realization of laser cooling and trapping of rubidium atoms.
