Abstract:

: We present an experimental demonstration of adaptive control of modal properties of optical beams. The control is achieved via heat-induced photothermal actuation of transmissive optical elements. We use conductive heating of a substrate via spatially selective application of heat using resistive electrical contacts. The system is capable of controlling both symmetrical and astigmatic aberrations providing a powerful means of correcting in-situ control of thermal aberrations in high power laser systems. We demonstrate a tunable lens with a focusing power varying from minus infinity to -10 m along two axes using SF57 optical glass. Applications of the proposed system include laser material processing, thermal compensation of high laser power radiation, and optical beam steering.
