Abstract
A diffractive microlens array was used to collimate a one-dimensional array of gain-guided AlGaAs lasers. The astigmatism of the lasers was removed by using anamorphic microlenses. The Strehl ratio of the resulting wavefront was 0.98. The microlens array was placed in an external cavity to produce a single coherent diffraction-limited beam from the AlGaAs laser array.
