本文报道了一种稳定光栅反馈半导体激光器在大范围内直接稳定到任意频率的方法。由波长计测得的频率与预设的目标频率之差产生的误差信号通过计算机中的声卡反馈到半导体激光器的压电换能器模块。开发了一个可视化的Labview程序来实现一个反馈系统。实验中，半导体激光器的频率漂移在25 min内被减小到8MHz。该方案可适用于许多其他类型的激光器实现任意频率稳定。
We report a robust method of directly stabilizing a grating feedback diode laser to an arbitrary frequency in a large range. The error signal, induced from the difference between the frequency measured by a wavelength meter and the preset target frequency, is fed back to the piezoelectric transducer module of the diode laser via a sound card in the computer. A visual Labview procedure is developed to realize a feedback system. In our experiment the frequency drift of the diode laser is reduced to 8 MHz within 25 min. The robust scheme can be adapted to realize the arbitrary frequency stabilization for many other kinds of lasers.
