Thermal operating conditions in an acousto-optic scanner

A theoretical analysis is made of the influence of the temperature gradients on the operation of Bragg-type modulators and deflectors for the control of high-power light fluxes. Isotherms are obtained for various sections through the active element by solving the heat conduction equation. The directions of the maximum temperature gradients in the active element are found for devices of this type. Some recommendations are made on future experimental investigations.
