Patent ID: 7586963

Claim:
A diode laser assembly comprising: a stepped cooling block, said stepped cooling block comprising a first cooling block section and an adjacent second cooling block section, wherein each of said first and second cooling block sections includes a plurality of stepped mounting surfaces of increasing height relative to a plane corresponding to a lowermost portion of a cooling block bottom surface, wherein adjacent stepped mounting surfaces of said first and second cooling block sections are non-coplanar with said stepped mounting surfaces of said first cooling block section positioned lower than said adjacent stepped mounting surfaces of said second cooling block section; a plurality of diode laser subassemblies, wherein each of said diode laser subassemblies is comprised of: a mounting block; an electrically insulating diode laser submount mounted to said mounting block, wherein said diode laser submount is comprised of an electrically insulating material; a diode laser mounted to said diode laser submount, wherein said diode laser is a single emitter diode laser; a first beam conditioning lens mounted to said mounting block, wherein an output beam from said diode laser passes through said first beam conditioning lens; and a second beam conditioning lens mounted to said mounting block, wherein a second output beam from a different diode laser subassembly of said plurality of diode laser subassemblies passes through said second beam conditioning lens; and means for mounting each of said plurality of diode laser subassemblies onto corresponding stepped mounting surfaces of said plurality of stepped mounting surfaces of said first cooling block section of said stepped cooling block, wherein each output beam from said plurality of diode laser subassemblies is displaced relative to an adjacent output beam.
