Investigation on noise-grating with the incident of plane monochromatic wave in (Ca0.28Ba0.72)x (Sr0.60Ba0.40)1−x Nb2O6 crystals

This investigation witnesses the fact that the direction of the light-induced self-diffraction spot changes with different Ca2+-doped CSBN ((Ca0.28Ba0.72)x (Sr0.60Ba0.40)1−x Nb2O6) crystals, indicating that the formed noise-grating wave vector direction changes with different ion-doped. Based on the wave optics theory and light-induced self-diffraction under the incident of plane monochromatic light wave in CSBN crystals, the theoretical model of noise-grating is analyzed, constructed and validated in this work.
