摘要
Coherent backscattering of light from a water suspension of zirconium silicate microcrystals is experimentallystudied.Optically controlled weak localization of photons is realized,which is due to the reorientation behaviors of positive uniaxial microcrystals induced by a linearly polarized pump beam.Because zirconium silicate particles are positive uniaxial microcrystals,their reorientation behaviors are contrary to negative ones.Our work widely extends the materials used in the light-controllable weak localization of photons.
