Abstract
This paper presents the results obtained by Intense during the development of its 2 kW stack using Quantum Well Intermixing (QWI). A 200 W QCW bar operating at 808 nm has been designed with a 1 mm long cavity of which only a fraction is actively pumped. The bar has an 80% fill factor, and ten 200 W bars were stacked vertically in a G-type package with a 417 μm bar-to-bar pitch. The resulting compact emission area makes the stack compatible with most existing laser and electro-optic systems. A lifetime of 1x10<sup>9</sup> shots has been obtained with no measurable degradation.
