Abstract:
1. Diode-laser apparatus, comprising: an electrically insulating, ceramic sub-mount having a high thermal conductivity and first and second opposite sides; a diode-laser bar solder-bonded to the first side of the ceramic sub-mount; a heat-sink assembly including a base-unit and a copper cooling-unit, each thereof having first and second opposite sides, the cooling-unit and the base-unit being attached together with the first side of the base-unit mating with the second side of the cooling-unit the copper cooling-unit having an integral mounting-member on the first side thereof, the second side of the ceramic sub-mount being solder-bonded to the mounting-member; the base-unit and the cooling-unit being cooperatively configured such that at least one cooling-channel having first and second opposite ends is formed in the cooling-unit by the attachment of the base-unit to the cooling-unit, with the cooling-channel arranged to cool the integral mounting-member when cooling-water flows therethrough; and the base-unit including an input-passage for directing water into the first end of the cooling-channel and an output-passage for conducting water away from the second end of the cooling-channel.
