Paper Abstract

In this paper, we propose a new type of Doppler discrimination system using an unseeded pulsed Q-switched laser and solid etalon. To substantiate our system, we calculate the transmitting spectral power distribution and discriminator characteristics. In our calculation, we use a 25 mm thick solid etalon with a finesse of 30, as well as a normal pulsed laser with a bandwidth of 1 cm-1. The results reveal that the change in the receiving scattered signal through the discriminator with a given LOS(Line of Sight) wind velocity is more sensitive than a normal iodine metal vapor-based Doppler lidar receiving system. We experimentally verify our suggestion using our Doppler discriminator and transmitter, and confirm that this combination is more sensitive than a metal vapor filter. Moreover, we suggest a more efficient transmitter and a more sensitive double-edge receiving system based on our calculations and experimental results.
