A New Method to Suppress the Fanning Noise in the Photorefractive LiNbO3:Fe Crystals

  • A new method to suppress the fanning noise caused by He-Ne laser in the cooperation with Ar+ laser in photorefractive LiNbO3:Fe crystal was successfully realized. This method is simple and efficient. By using this method, fanning-noise-free hologram can be stored in LiNbO3:Fecrystal.
