Patent ID: 7929585

Claim:
A system comprising: a laser diode comprising: an array of semiconductor active regions disposed between two at least partially transmissive facets; an optical subsystem optically disposed to receive electromagnetic radiation emitted from one of said two partially transmissive facets; and a phase conjugating reflective component optically disposed to receive electromagnetic radiation from said optical subsystem; said optical subsystem imaging the electromagnetic radiation emitted from said one of said two partially transmissive facets onto said phase conjugating reflective component; said phase conjugating reflective component providing phase conjugated reflected electromagnetic radiation to said optical subsystem; said optical subsystem providing at least a portion of said phase conjugated reflected electromagnetic radiation to said laser diode; and electromagnetic radiation resulting from propagation of at least a portion of the electromagnetic radiation, provided by said optical subsystem to said laser diode, through the array of semiconductor active regions being emitted by another facet from said two at least partially transmissive facets; said laser diode being an only source of said phase conjugated reflected electromagnetic radiation; the electromagnetic radiation received by said phase conjugating reflective component being coherent; said phase conjugating reflective component and another one of said two at least partially transmissive facets forming a laser resonator.
