Research on Multi-wavelength Laser Propagation Effects in Marine Atmospheric Boundary Layer

在沿海某地区的海面大气边界层中进行了距离分别为0.5km、1.0km和3.0km的激光大气传输效应研究,通过对可见光(0.473μm、0.532μm和0.671μm)和中红外(3.8μm)波段激光传输实验测量,得到了海面大气边界层内多波段激光传输的光强起伏、光束漂移和大气衰减。此外,光传输光强起伏的频谱分析进一步揭示了不同波段的激光在海面上传输的独特性.

Experimental research on laser propagating along an atmospheric path of 0.5 km, 1.0 km and 3.0 km was carried out in a marine surface layer. The characteristics of optical intensity fluctuation, beam wandering and atmospheric extinction were analyzed by a series of laser propagation tests at the visible （0.473 μm, 0.532 μm and 0.671 μm） and mid-IR （3.8 μm） wavelength. Besides, the spectral analysis of optical intensity fluctuation reveals that the unique property dependent on the wavelength exists for laser propagation in the marine atmosphere.
