恒压驱动对激光阵列起爆系统性能的影响

摘要

In order to solve the problems of large volume and light energy loss of the traditional multi-channel laser initiation system, the laser array initiation circuit based on a constant-voltage drive mode was designed. The influence of constant -voltage drive mode on the whole initiation system was verified, by the experimental results of laser array synchronization test and detonation performance test, and the corresponding improvement measure was also put forward. The result shows that the constant-voltage drive mode can realize the multi-channel selection and sequential logic initiation, using average current method can reduce the synchronous output difference of the multi-channel laser.%为解决传统的多路激光起爆系统体积大、光能量损失的问题，设计了一种基于恒压驱动模式的激光阵列起爆电路。通过激光阵列同步实验、起爆性能实验验证了恒压驱动模式对整个起爆系统的影响，并对恒压驱动提出了改进措施。结果表明恒压驱动模式能够实现多路选择、时序逻辑起爆，采用均流法可减小多路激光同步输出的差异性。
