Patent ID: 7848372

Claim:
A diode laser assembly comprising: a cooling block comprised of a plurality of stepped mounting surfaces of increasing height relative to a plane corresponding to a lowermost portion of a cooling block bottom surface; a plurality of diode laser subassemblies, wherein each of said diode laser subassemblies is comprised of: a mounting block, wherein said mounting block does not include integral coolant passages; an electrically insulating 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 wherein a fast axis of said diode laser is perpendicular to a diode laser mounting surface of said diode laser submount; a first beam conditioning lens mounted to said mounting block, wherein an output beam from a diode laser exit facet of said diode laser passes through said first beam conditioning lens, wherein said first beam conditioning lens reduces beam divergence in said fast axis; and a second beam conditioning lens mounted to said mounting block, wherein a second output beam from an adjacent diode laser subassembly of said plurality of diode laser subassemblies passes through said second beam conditioning lens, wherein said second beam conditioning lens reduces beam divergence in a slow axis of said diode laser; and means for mounting said plurality of diode laser subassemblies onto said plurality of stepped mounting surfaces of said cooling block, wherein each diode laser exit facet corresponding to said plurality of diode laser subassemblies is displaced along the z-axis relative to an adjacent diode laser exit facet, wherein each diode laser exit facet corresponding to said plurality of diode laser subassemblies is displaced along the y-axis relative to said adjacent diode laser exit facet, wherein each diode laser exit facet corresponding to said plurality of diode laser subassemblies is not displaced along the x-axis relative to said adjacent diode laser exit facet, wherein said slow axes of said diode lasers corresponding to said plurality of diode laser subassemblies are parallel to one another and to said x-axis, and wherein said fast axes of said diode lasers corresponding to said plurality of diode laser subassemblies are parallel on one another and to said z-axis.
