Abstract
We demonstrate the beam smoothing by polarization control plate (PCP) produced by liquid crystal. The liquid crystal PCP using photoisomerization of the azo-dye was developed. The PCP is constructed by 14 X 14 array of 2 mm X 2 mm square element. The damage threshold is about 12 J/cm2 (532 nm, 0.9 ns). The PCP suppressed the speckles produced by a random phase plate. The contrast of the speckles is reduced at 30% by a PCP.
