A new method is proposed in which uniaxial crystal is used to fabricate the phase plate, with which shaping and polarization smoothing of the target focal spot can be achieved simultaneously in the laser driver of inertial confinement fusion. The principle of crystal phase plate (PS-CPP) is analyzed using the scalar diffraction theory. The solution of crystal surface shape is obtained from the distribution characteristics of the focal spot. Numerical simulation is developed to analyze the application of PS-CPP. The results show that under the conditions of particular crystal cutting angle and surface shape, PS-CPP can be obviously effective for focal spot shaping and smoothing, and the effectiveness is as good as that of the combination of continuous phase plate and the polarizing smoothing crystal.
