强激光大气传输时的湍流效应

The turbulence effect of high power laser propagation in the atmosphere

强激光通过大气环境后,在目标处希望得到振幅与相位未畸变的激光束.大气环境,尤其是大气湍流状态是对其有根本性影响的历史性难题.激光系统的设计和使用中必须要考虑这些问题.本文对湍流中标量场的标度指数、统计分布及激光在大气中传播等问题中提出几个值得研究的问题.

The high power laser beams are expected to be obtained in the target with the amplitude and phase undisturbed after going through the atmosphere. The atmospheric circumstances, especially the atmospheric turbulence situation are essential to laser propagation. They are very difficult historical problems. These problems have to be considered in designing and using the laser system. In this paper, the central contents are to advocate some valuable problems with respect to the scale exponent of scalar field, stochastic distribution and laser propagation in atmosphere.
