The development and operation of a kilowatt scale KD(asterisk)P second harmonic generator is described. The design utilizes a simple and compact two-plate alternating-Z configuration with a transverse thermal gradient. The calculated single pulse conversion efficiency is between 50 and 75 percent for beams whose divergence is up to 15 times the diffraction limit. Offline subaperture tests demonstrated that the effect of induced thermal gradients on conversion efficiency was less than 5 percent for optical loads expected for kilowatt operation. Full aperture tests with a 300 watt average power Nd:glass zigzag slab laser gave conversions of 35 percent.
