标题： Comment: Anomalous Anisotropic Light Scattering in Ge-Doped Silica Glass

摘要： 这是一个对Kazansky等人论文的评论，发表于Phys. Rev. Lett., 82, 2199 (1999)。我们证明了在超短激光脉冲光场中振荡的光电子的制动辐射解释了Kazansky等人论文中描述的异常各向异性光散射，“螺旋桨效应”。这种发光机制可以解释白光连续谱生成和介质击穿辐射的一些结果。 显示英文摘要

摘要： This is a comment on a paper by Kazansky et al. appeared in Phys. Rev. Lett., 82, 2199 (1999). We demonstrate that the bremsstrahlung of photoelectrons, which oscillate in the light field of an ultrashort laser pulse, accounts for the anomalous anisotropic light scattering, the "propeller effect", described in the paper of Kazansky et al. This mechanism of light emission could explain some results of white-light continuum generation and dielectric breakdown emission.
