摘要
为了便于连续变量量子光学实验研究,我们设计了基于微控制器(MCU)的自动锁定控制系统,可以用于光学模清洁器腔长的自动锁定。该系统利用模数转换识别信号,通过MCU完成相关数据分析和计算,再由数模转换完成信号输出,实现了系统的自动锁定,而且在失锁发生后,系统能自动切换工作模式,实现模清洁器的重新锁定,完成重新自动锁定所需时间基本小于0.1 s,其锁定之后激光功率波动小于1%。
In order to facilitate the operability of continuous variable quantum optical experiment, an automatic locking system with microcontroller(MCU) is designed and is used in the cavity length locking of the optical mode cleaner. We use analog to digital conversion to identify the signal, the MCU to complete the relevant data analysis and calculation, and then digital to analog conversion to complete the signal output. Finally, the automatic locking of cavity length is realized. When the cavity is unlocked, the system can automatically switch working mode to achieve re-locking. The re-locking time is less than 0.1 s, and the fluctuation of intensity is less than 1%.
