Abstract
We describe the fabrication of variable reflectivity gratings by an holographic technique and the use of such components as mode selectors in lasers. Gratings with a spatially variable reflectivity profile are produced by the interference of two Gaussian beams on a photoresist material deposited on glass. The gratings have been tested with a Nd: YAG laser and a broad-area semiconductor laser; the beam shape and the modal content of the lasers were improved when the gratings were used as output couplers.
