Abstract
An extremely versatile diode laser assembly is provided, the assembly comprised of a plurality of diode laser subassemblies mounted to a stepped cooling block. The stepped cooling block allows the fabrication of a close packed and compact assembly in which individual diode laser subassembly output beams do not interfere with one another.
Claims17
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 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 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 higher 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;
- 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 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.
