Paper Abstract

Mirrors with a super-Gaussian reflectivity profile are extremely useful for high power laser design with nearly diffraction limited output beams. The super-Gaussian mirrors are usually realized by dielectric mirrors with one or more tapered layers. Taking advantage of the thermo-optical effect we propose to build tapered mirrors and windows, the optical parameters of which can be electrically modulated. The most relevant result is that these devices can be easily employed to realize super-Gaussian mirrors with an electrically adjustable reflectivity profile.
