| 摘 要： | 为了研制一种用于抽运单频单块激光器的LD电源,采用恒流电路对LD进行驱动,并应用软件监测的方法对电流的长期稳定性和故障进行监测和调节.运用模糊和比例-积分-微分(PID)混合控制温度调节算法,具有超调小和控制精度高的优点,并对基本PID算法进行了简化.使用了一个分段取值的参数,在控制范围内使运算速度提高10倍以上.实验结果表明,实现LD驱动电流的稳定度优于2 mA,LD温度长期波动小于0.1℃,激光输出的频率在一定温度范围内连续可调.

| Abstract: | A LD power supply for pumping the monolithic laser is developed and driven by constant current circuit. Software monitoring is applied to test and adjust long period stability and fault of current. Temperature adjustment arithmetic of fuzzy and proportional-integral-derivative(PID)control is used to gain small overshoot and high control precision. Basic PID arithmetic is simplified by using a subsection chosen value to improve the operation speed more than ten times. Continuously frequency adjustable laser is realized in a certain temperature range,whose current stability is less than 2mA,lasting temperature fluctuation is below 0.1℃. |
