We have constructed a 180-m-long distributed, continuously variable atmospheric turbulence generator to study high-power laser beam propagation. This turbulence generator operates on the principle of free convection from a heated surface placed below the entire propagation path of the beam, similar to the situation in long-distance horizontal propagation for laser communications, power beaming, or directed energy applications. The turbulence produced by this generator has been characterized through constant-temperature anemometry, as well as by the scintillation of a low-power laser beam.
我们构建了一台180米长的分布式、连续可变大气湍流发生器，用于研究高功率激光束的传播。该湍流发生器基于放置在光束整个传播路径下方的受热表面的自由对流原理运行，类似于激光通信、功率传输或定向能应用中的长距离水平传播情况。该发生器产生的湍流已通过恒温风速测量以及低功率激光束的闪烁进行了表征。
