| 摘 要： | 搭建了声光调Q脉冲光纤激光器实验 系统,通过调节声光调制器(AOM)驱动信号的占空比,研 究了驱动信号占空比对声光调Q脉冲光纤激光器输出脉冲重频的影响。结果显 示,当AOM驱动信号频率 固定时,随着占空比的减小,输出脉冲重频依次为AOM驱动信号频率、AOM驱动信号频率的1/ 2、1/3。 实验结果表明,在声光调Q脉冲光纤激光器中,输出脉冲重频受A OM驱动信号频率和占空比的共同影响。

| Abstract: | An acousto-optic Q-switched pulsed fiber lase r experimental system is set up and the influence of the duty cycle of the drivin g signal on the output pulse repetition frequency is demonstrated by adjusting the duty cycle of the driving signal of the acousto-optic moudulator (AOM).The results show that when the frequency of the driving signal is fixed,the output pulse appears at the fi rst,and then third sub-harmonics of the AOM repetition rate in order with the decrease of the duty cycle of the driving signal.The experimental results show that appear in an acousto-optic Q-switched pul sed fiber laser,the output pulse repetition frequency is influenced by the frequency and the duty cy cle of the AOM driving signal at the same time. |
