Abstract

We have developed an extremely stable phase conjugate single-mode laser diode array with unique spatial and temporal coherence properties. The laser is based on a novel concept of frequency selective phase conjugate feedback. A laser diode array is coupled to the phase conjugate feedback system that comprises a rhodium doped BaTiO₃ crystal, a Fabry-Perot etalon, and a spatial filter. This feedback system forces the laser diode array to operate in a single spatial and a single longitudinal mode. In comparison with the free running laser diode array, the coherence length is increased significantly and the output is close to the diffraction limit. More than 80% of the total energy provided by the free running laser diode array can be extracted from this single-mode laser system.
