Diffraction-limited operation from monolithically integrated diode laser array and self-imaging (Talbot) cavity

Abstract

The monolithic integration of a linear array and a separately pumped self-imaging Talbot cavity has resulted in diffraction-limited single-lobe output beams to output powers in excess of 100 mW/facet. A study was made of the device operation as a function of the drive currents applied to the array region and the Talbot cavity.
