title: Variable spot-size waveguide for laser printing.
abstract: A variable-spot-size Ti-LiNbO(3) waveguide that permits electro-optical longitudinal shifting of the focal point is described. A 70% spot-size increase is observed for the ±60-V power supply. This spot-size variation technique is used in a basic experiment on halftone laser printing.
