LASER DIODE MODULE WITH INTEGRAL COOLING

摘要

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 (32) mounted centrally therein. A cooling channel (62) is in thermal relation with the array (32) either directly or via a diamond substrate. A fiber optic coupler (46) mates with the portion of the housing carrying the array and carries a lens subassembly (16, 18). During assembly, the coupler (46) is positioned to accurately focus the output of the array into a beam suitable for transmission to the fiber optic cable.
