Patent ID: 7436868

Claim:
A diode laser assembly comprising: a stepped cooling block, said stepped cooling block comprising at least a first continuous cooling block section, a second continuous cooling block section, and a third continuous cooling block section, wherein each of said first, second and third cooling block sections is comprised of a continuous plurality of stepped mounting surfaces aligned in a row and of increasing height relative to a plane corresponding to a lowermost portion of a cooling block bottom surface, wherein said first cooling block section is interposed between said second and third cooling block sections, and wherein said first cooling block section is recessed relative to said second and third cooling block sections; a plurality of diode laser subassemblies, wherein each of said diode laser subassemblies is comprised of: a mounting block; an electrically insulating a diode laser submount mounted to said mounting block, wherein said diode laser submount is comprised of an electrically insulating material; and a diode laser mounted to said diode laser submount, wherein said diode laser is a single emitter diode laser; and means for mounting each of said plurality of diode laser subassemblies onto corresponding 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.
