摘　　要：研制了一种基于计算机控制的电调谐半导体激光器波长控制系统。通过调用系统中的半导体激光器“波长-电流”数据查询表,控制驱动单元的电流输出,实现对半导体激光器的输出波长控制。应用该系统对DBR激光器进行了波长控制实验,其波长控制误差不超过±0.02 nm。A computer-based control system used for the wavelength tuning of current tunable semiconductor lasers is developed.According to the look-up table which is used by the system to record the relationship between the wavelength and tuning currents, the particular lasing wavelength of semiconductor laser is obtained by controlling the output currents of the driver element. With this system,wavelength control experiments of the distributed Bragg reflector（DBR） laser are accomplished. And it is shown that the error of wavelength control is not more than ±0.02 nm.
