Abstract

The search for higher levels of coherent power from semiconductor lasers has given rise to various approaches for phase locking of laser diode arrays. These approaches fall into two broad categories: (1) on-chip locking of 1-D edge emitting and 2-D surface emitting arrays and (2) phase locking using an external cavity. Spatially sparse laser diode arrays locked in an external cavity consisting of a fiat mirror and appropriate spatial or phase filters placed in the self-image planes of the array are promising candidates for generation of coherent power. This design is particularly attractive when one considers applications requirements such as scalability, heat removal, mode control, and fill-factor enhancement. We demonstrate selection of single array modes and enhancement of an array fill factor by self-imaging cavities.
