Abstract

For a diode laser subjected to feedback from a phase- conjugating mirror we present (1) the first exact stability- analysis and (2) various spectra. The stability properties are intermediate between those of the injection laser and the laser with conventional optical feedback. The role of a finite response-time is to drastically enhance the steady- state stability. For moderate feedback the frequency noise is suppressed by several orders of magnitude, and the main relaxation frequency of the laser shows a crossover from the usual relaxation oscillation frequency to a new frequency determined by the amount of feedback. This may be of technological importance since it improves the modulation bandwidth.
