Abstract	采用双声光调制器光路快速偏转技术与自准直光栅法实现CO_2激光全波段快调谐同光路输出。首先对声光调制器特性进行实验研究,结果显示:声光调制器偏转角度约为4. 4°,与运用布拉格方程计算结果相符;且激光单次通过声光调制器移频量为40. 68 MHz,与声光驱动器射频频率一致,将激光往返多次经声光调制器的移频量叠加。进而,开展基于声光调制器的CO_2激光快调谐实验研究,运用两个对称布置的同驱动频率声光调制器补偿声光移频,实现偏转光路振荡输出,运用光栅法在直线光路中实现激光全波段可调谐输出。最终,在声光调制器时序控制下,实现双波长激光快调谐同光路输出,选定激光波长的切换时间约为1 ms,脉宽小于300 ns,且双波长切换速度不受CO_2激光跃迁谱带的限制。
