分析了高强度反向传播辐射脉冲引起的超相对论非线性介质不均匀性引起的多普勒频移导致电磁辐射频率显著上转换的可能性。结果表明，参数重分布的效率共振增加的速度接近高频辐射的相速度的不均匀性。
The possibility of a significant up-conversion of the electromagnetic-radiation frequency due to its Doppler shift by ultrarelativistic nonlinear-medium inhomogeneities induced by high-intensity counterpropagating radiation pulses is analyzed. It is shown that the efficiency of parametric redistribution increases resonantly as the velocity of the inhomogeneity approaches the phase velocity of the high-frequency radiation.
