An operating 2 × 2 Nd:YAG digital scan laser containing a crossed array of LiNbO3electrooptic switches for mode selection is described. Ultimate output parameters for a complete system include a 1-watt power output to any of approximately 7 \times 10^{3} spots, with MHz switching speeds. The required mode-selection voltage is under 100 volts, permitting the use of fast transistorized driving circuitry.
