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.
