Investigations of the diffraction efficiency in dye-doped LC cells under low frequency AC voltage

Grudniewski T., Parka J., Dąbrowski R., Januszko A., Miniewicz A.

Opto-Electronics Review

2002

Vol. 10, No. 1

In this paper, relation between the diffraction efficiency in LC dye doped cell in two wave mixing system and the applied voltage parameters had been described. The goal of this work was increase in diffraction efficiency using low frequency AC voltage. The LC cells used in the experiments were filled with pure and dye-doped liquid crystal mixtures. In this system, we obtained diffraction efficiency increasing about five to eight times.
