Abstract为了解决非注入状态激光脉冲对非相干多普勒激光雷达测风结果可靠性的影响,利用注入与非注入状态激光脉冲建立时间不同的原理,设计和实现了一种脉冲激光种子注入状态检测器,其时间测量精度为45ps,测量时间范围为3.5ns~2500ns,最高脉冲重复频率为1kHz。利用该检测器对某型号Nd:YAG脉冲激光器进行了种子注入状态检测实验,结果显示注入(非注入)状态脉冲建立平均时间为123.27ns(134.44ns),1.35h内非注入状态激光脉冲占总激光脉冲比例为8.54%。结果表明,该脉冲激光种子注入状态检测器能够有效地检测出非注入状态的激光脉冲,对于提高激光雷达测风可靠性具有潜在的价值。
Other AbstractTo avoid the influences of unseeded laser pulses on wind speed measurement of incoherent Doppler wind lidar, a detector of pulse laser injection seeded state was designed and implemented based on the principle of different laser pulse building time of the injection seeded and unseeded state. The time measurement accuracy of the detector was 45ps, time measurement range was from 3.5ns to 2500ns, and the highest pulse repetition rate was up to 1kHz. The experiment of injection seeded state detection was conducted with the detector. The results show that laser pulse building time of the injection seeded state is 123.27ns, less than 134.44ns of the unseeded state. The proportion of injection unseeded laser pulses to total laser pulses is 8.54% within 1.35h. The pulse laser injection seeded state detector can effectively detect and discriminate the injection seeded and unseeded laser pulses. The detector has a potential value to improve wind speed measurement reliability of Doppler wind lidar.
