The diffraction properties of transient holographic gratings recorded by two 532 nm laser beams were investigated in nematic liquid crystals doped with Disperse Red 1. A nearly 30-fold enhancement of the first-order diffraction efficiency as a function of heating time was obtained when the sample temperature was close to the clearing point in the nematic phase. A peak shift of diffraction efficiency with the increase of recording light intensity was observed, which was attributed to laser induced photochemical nematic-isotropic phase transition.
