摘要

着重讨论了不同参数对室内传输通道热晕效应的影响.数值计算的结果表明:对于理想光束,即使在10 kW的激光功率情况下,传输距离大于25 m,吸收系数大于0.013 km-1时,就需要考虑室内传输通道热晕效应对光束质量的影响.随着吸收系数的增大,传输距离的加长,激光功率的提高,通道内热晕效应的影响越来越严重,应采取一定的措施来减小室内传输通道热晕效应.

Abstract

The effect of different parameters on the thermal blooming for laser channel transmission is described. The numerical results suggest that the effect of thermal blooming on the beam quality for laser channel transmission must be considered, when the initial beam quality factor is 1, the beam power is 10 kW, the propagation length is 25 m and the absorption coefficient is greater than 0.013 km-1. When the absorption coefficient, the propagation length and the beam power are increased , the thermal blooming becomes gradually strong and some methods should be used in order to decrease it.
