The authors studied the coupling properties of laser diode arrays to photorefractive phase-conjugate mirrors. They succeeded in locking two different laser arrays, even where the uncoupled lasers' wavelength detuning was 10 angstrom. By controlling the array's modal gain using a variable slit in the cavity, it was possible to switch the array from its preferential highest supermode with a twin-lobe far-field pattern to the single-lobed mode. Results suggest ways to lock several arrays together and control their far-field patterns.
