Abstract: Optical output beams from a vertical stack of diode-laser bars are focused by a simple focusing lens on an optical axis of the lens. The optical output beams from outlying diode-laser bars in the vertical stack are tilted with respect to the optical axis of the focusing lens such that optical output from the whole vertical stack is brought to a common focus location on the optical axis of the focusing lens.

Abstract: A diode-laser assembly having an electrically isolated diode-laser bar on a cooled base-element is disclosed. The diode-laser bar is electrically isolated from the base-element and electrically isolated from any coolant water, thereby eliminating the need for de-ionized water and mitigating corrosion due to galvanic action. Multiple such diode-laser assemblies are stackable, with small bar-to-bar pitch, enabling a high-current and high-brightness diode-laser stack.

Abstract: A water-cooled heat-sink for a diode-laser bar includes a copper-cooling-unit having an integral mount thereon for the diode-laser bar. The copper-cooling-unit is attached to a steel base-unit. The base-unit and the cooling-unit are cooperatively configured such that at least one cooling-channel is formed in the cooling-unit by the attachment of the base-unit to the cooling-unit. The cooling-channel is positioned to cool the mount when cooling-water flows through the cooling-channel.

Abstract: A diode-laser bar is mounted on water-cooled heat-sink between two ceramic sub-mounts for electrically isolating cooling-water in the heat-sink from the diode-laser bar. Mounting between the two ceramic sub-mounts also provides for balancing stresses due to differences in coefficient of thermal expansion (CTE) between the sub-mounts and the diode-laser bar. Both sub-mounts are in thermal communication with the heat-sink for providing two-sided cooling of the diode-laser bar.
