Abstract

Summary form only given. It is well known that the scattering of polarized light in the plane of light polarization in an isotropic medium such as glass is always weaker compared to the orthogonal plane, since a dipole does not radiate in the direction of its axis. We report here the observation of a new phenomenon in glass pumped by intense laser radiation-the scattering of light, in particular luminescence, which peaks in the wrong plane-in the plane of light polarization (anomalous anisotropic light scattering).
