摘要
介绍了大功率激光脉冲系统中声光开关部件的组成原理和构成方式。该部件在外接同步信号触发下迅速开启光路,并在80ns后关闭,从输入的一串光脉冲中捕捉到某个光脉冲,并输出至下一级传输系统。该声光开关部件具有良好的信噪比特性,在大功率激光脉冲系统中有良好的应用前景。
The composition principles and construction mode of an acousto-optic switch in a high power laser pulse system is introduced. The system rapidly unblocks the path of ray triggered by external clocking signal, and rapidly closes after 80 ns. The action of the component catches a certain pulse from a string of pulses on the input port, then outputs the laser pulse to the next stage of transmission system. This acousto-optic switch is provided with good signal-to-noise ratio, and has good application prospect in high power laser pulse system.
