Beam coupling and coherent amplification in photorefractive liquid crystals under ac electric field

Not Accessible

Your library or personal account may give you access

Abstract

Two-beam coupling phenomenon in C60-doped nematic liquid crystals under a nonbiased alternating sinusoidal electric field was studied. The stable asymmetric energy transferring and large beam coupling ratio was obtained. Then the coherent amplification was realized.
