本文分析了极性环境起伏对偶极分子在强电磁场中共振产生高次光学谐波的影响。被认为是缓慢和强烈的环境波动的情况下。结果表明，由介质的偶极矩波动产生的电场导致的散射辐射强度的温度依赖性异常。在慢涨落和一些附加条件下，谐波强度随温度呈指数增长。相反，在精确共振条件下的快速波动的情况下，谐波强度随着温度的升高而降低。在分子的非共振激发下，极性介质对高次谐波的产生没有影响。
An analysis is made of the effect of fluctuations of a polar environment on the resonant generation of higher optical harmonics by dipole molecules in a strong electromagnetic field. The cases of slow and strong fluctuations of the environment are considered. It is shown that the electric fields produced by fluctuating dipole moments of the medium lead to anomalous temperature dependences of the scattered-radiation intensity. In the case of slow fluctuations and some additional conditions, the harmonic intensity exponentially increases with temperature. In contrast, in the case of rapid fluctuations under exact resonant conditions, the harmonic intensity decreases with increasing temperature. Under nonresonant excitation of molecules, a polar medium has no effect on the generation of higher harmonics.
