摘要：设计了一种同步时序控制系统，可实现脉冲激光能量探测过程的自动化开关控制，并保证每次测量过程中参与积分的激光脉冲数目相同。设计了激光脉冲计数电路，结合锁存器、比较器产生预置脉冲频率的启动测量信号，将其输入到所设计的基于D触发器的同步时序控制电路中，获得该脉冲频率的同步控制信号，即可实现脉冲激光能量探测过程的同步自动化控制。通过同步控制过程分析验证了该系统的可行性，可满足脉冲激光能量探测的控制需求。

Abstract:A synchronous timing control system is designed to realize the automatic switch control of the pulsed laser energy detection process，and to ensure that the number of laser pulses participating in the integration is the same during each measurement.A laser pulse counting circuit is designed，which combines the latch and comparator to generate the start measurement signal of preset pulse frequency.By inputting it into the synchronous sequential control circuit based on D flipflop designed，the synchronous control signal of the pulse frequency can be obtained，and the synchronous automatic control of the pulse laser energy detection process can be realized.The feasibility of the system is verified by analysis of the synchronous control process，which meets the control requirements of the pulse laser energy detection.
