Vertically displaced stack of multi-mode single emitter laser diodes

摘要

An optical source comprised of a stack of at least two laser diode subassemblies is provided. Each laser diode subassembly includes a submount and a multi-mode, single emitter laser diode. Each of the at least two laser diode subassemblies is mounted to a mounting member. Means are included to vertically displace the output beams from the individual laser diode subassemblies to form an optical source output beam. In at least one embodiment, the mounting member performs the function of the vertically displacing means.
