This paper reviews technology issues relating to the construction and operation of efficient two dimensional close-packed arrays at the multi-kilowatt level. This involves detailed consideration of the properties of the multiple RF discharges, thermal engineering and material requirements, and issues related to the optical resonator design. Performance in terms of power scaling, discharge and gas pressure/mixture and spectral characteristics for planar and 2-d array lasers is discussed. Experimental measurements of the beam propagation characteristics of multiple identical waveguide laser array elements are described and compared with theoretical predictions. In addition, experiments are discussed which involve the use of diffractive optical elements for spatially reformatting the linear beam profile produced by planar laser arrays.
