An experimentally determined coupling coefficient for a singlemode diode laser operated with conventional optical feedback is contrasted with that for phase conjugate feedback. Values are determined to be 0.2 ± 0.05, and 0.7 ± 0.1, respectively. These quantitative measurements indicate the enhancement in coupling efficiency that can be achieved using a phase conjugate reflector.
