Abstract
A modulator for a high optical power printing includes a transparent crystal and a patterned buffer layer formed over one of the surfaces of the crystal. An electrode array is formed so that each electrode of the electrode array is patterned directly on each portion of the patterned buffer layer. In a further feature of the invention, the crystal substrate can be formed so that opposing endfaces through which high optical power laser light passes are at an angle and are antireflection coated. A transparent and electrically insulating overcoat is provided above the electrodes.
