Abstract—

General formulas for the extinction coefficient of laser radiation in an atmosphere are derived. They take into account nonlinear effects and significantly differ from the linear optics results. Specific calculations are carried out for the atmosphere of Titan. It is shown that consideration of a close-to-real altitude dependence of the concentration of atmospheric gases leads to the altitude dependence of the extinction coefficient being significantly different from the results obtained using the barometric formula. The extinction coefficient in the atmosphere of Triton is also estimated.

泰坦大气中的激光辐射吸收

摘要—

推导了大气中激光辐射消光系数的一般公式。它们考虑了非线性效应，并且与线性光学结果大不相同。针对泰坦大气进行了特定的计算。结果表明，考虑到大气中气体浓度与实际海拔高度的相关性，导致消光系数与海拔高度的相关性与使用大气公式得出的结果明显不同。还估计了特里顿大气中的消光系数。
