Abstract
Disclosed herein are embodiments of a vertical external cavity surface emitting laser (VECSEL) device that utilizes an external micromirror array, and methods of fabricating and using the same. In one embodiment, a VECSEL device includes a gain chip, a mirror, and a micromirror array. The gain chip includes a gain medium. The micromirror array includes a plurality of curved micromirrors. The micromirror array and the mirror define an optical cavity, and the micromirror array is oriented such that at least one of the curved micromirrors is to reflect light generated by the gain medium back toward the gain medium along a length of the optical cavity.
