We present kW QCW vertical and horizontal arrays composed of 200W bars (peak power) at 8xxnm wavelength. We also present an unique Bar-on-Submount design using the electrically insulating submounts, which can provide a platform for simple and flexible horizontal array construction. The p-n junction temperature of the arrays under QCW operation is modeled with FEA software, as well as measured in this research. Updated reliability test results for these kW arrays will be also reported. As the examples, we present the performance of the vertical arrays with > 57% Wall-Plug-Efficiency and the horizontal arrays with < 23 degree fast axis divergence (FWHM), both with 808nm wavelength. The available wavelength for such arrays ranges from 780nm to beyond 1 um. Coherent also have the capability to produce the array with wide and relatively uniform spectrum for athermal pumping of solid-state lasers, by integrating diode lasers bars with different wavelength into single array.
