摘要
设计并实现了一个高精度的半导体激光器驱动系统，该系统包括温度控制和电流控制两部分。温度的控制范围为室温下±1．50×10^1K，控温精度优于1．81mK，标准差小于0．20mK。电流的调节范围为0～2．00×10^2mA，纹波小于1．00×10^2nA。该系统驱动外腔半导体激光器时可以保证激光器输出的频率稳定度在10s内达到1．00×10^-9，满足原子分子物理和激光光谱学等领域对高精度激光器的需求。
A high-precision driving circuit was designed and realized for semiconductor lasers, which has two parts of temperature control and current control. The temperature is controlled in the range of ± 1.50 ×10^1K at room temperature, the temperature control precision is better than 1.81 mK, and the standard deviation is less than 0.20 mK. The current adjusting range is 0 to 2.00 ×10^2 mA and the ripple is less than 1.00 ×10^2 hA. When used for driving a semiconductor laser, the system can make the output frequency of the laser diode reach 1.00 × 10^-9 within 10 s, which can meet the requirements of atom molecule physics, laser spectroscopy, and other fields to high-precision lasers.
