A coherent beam coupled laser diode array includes an array of laser diodes. Each diode emits a beam propagating along a beam path. An array of collimation optics is included. Each of the collimation optics collimates one beam. A first lenslet array is included. Each lenslet refracts a portion of one beam and a portion of a different beam from the array. A partially reflecting mirror is included. A first portion of each beam propagates through the partially reflecting mirror and a second portion of each beam is reflected back toward the first lenslet array. The second portion of each beam reflected propagates back through the first lenslet array and the collimation optics and into one of the diodes in the array of laser diodes, thereby creating an optical cross coupling. A second lenslet array collimates each beam propagating through each lenslet to form a single laser beam.
