We demonstrate laser beam shaping by utilizing the linear electro-optic effect in patterned ferroelectric domains in lithium tantalate. The phase function essential for the conversion of a 633 nm wavelength laser light from a Gaussian to a flat-top intensity profile was computed using the Gerchberg-Saxton algorithm. The corresponding ferroelectric domain pattern required to induce the equivalent phase function was fabricated on a lithium tantalate crystal, and the performance compared with design specifications.
