影响激光传输效果的主要因素包括大气分子和气溶胶粒子吸收以及由散射造成的衰减效应、大气湍流引起的湍流效应和强激光加热空气造成的热晕效应。针对光纤激光的大气传输进行了研究,研究了在1080nm特定波长的光纤激光大气传输过程中的大气湍流、热晕效应、湍流热晕相互作用对光纤激光远场功率密度的影响。
The main factors affecting the laser transmission include the absorption of atmospheric molecules and aerosol particles, the attenuation effect caused by scattering, the turbulence caused by atmospheric turbulence and the thermal halo effect caused by intense laser heating of air. The effects of atmospheric turbulence, thermal halo effect and turbulent thermal halo interaction on the far-field power density of fiber laser were studied in the atmospheric transmission of fiber laser at a specific wavelength of 1080 nm.
