摘要：声光调制器是一种重要的光学器件,其性能在很大程度上依赖于驱动源的性能。因此,针对不同的应用场景,研制高性能的声光调制器驱动源具有重要意义。本文针对量子光学领域真空压缩光制备中光学参量振荡腔腔长锁定对声光调制器的应用需求,设计了一款高性能声光调制器驱动源。该驱动源以射频金属氧化物半导体(MOS)场效应管放大模块RA07H0608M为核心器件,输入信号经阻抗匹配电路、高通滤波放大电路、功率放大电路后,最终输出到声光调制器中,同时,监测电路对工作温度和信号功率进行实时监测。实验结果表明,该声光调制器驱动源能够实现频率和功率的连续调谐,在75~85 MHz的工作频率范围内,输入输出信号具有良好的线性关系,输出功率高达1 W,并且同时具有超温和超功率自动关断保护功能,完全满足声光调制器长时间稳定运行的要求。
