Abstract

The use of an external cavity consisting of an array of binary optic microlenses and an output mirror to obtain coherent beam addition of 2-D laser diode arrays has been investigated. The thresholds of the in-phase and out-of-phase lateral modes of the external cavity have been measured as a function of mirror spacing. The results indicate that the out-of-phase mode is more stable. A miniature external cavity has been designed to lase in the out-of-phase mode and has been applied it to a 1-D laser array. The results are presented and discussed.
