Abstract
A laser module with integral cooling is disclosed. The module is intended for coupling to a fiber optic cable for various applications. The module is generally cylindrical and has a laser diode array mounted centrally therein. A cooling channel is in thermal relation with the array either directly or via a diamond substrate. A fiber optic coupler mates with the portion of the housing carrying the array and carries a lens subassembly. During assembly, the coupler is positioned to accurately focus the output of the array into a beam suitable for transmission to the fiber optic cable. Coolant is coupled to the channel with a removable coupling manifold or similar arrangement which may also carry electrical contacts for energizing the array.
