The upper limit of the frequency range of a broadband optical receiver of surface acoustic waves based on a two-beam laser interferometer and depending on the diameter of the laser beam in the reception area on the sample surface is determined theoretically and experimentally. It is shown that the frequency range of the developed receiver is 0.05–53 MHz and in the limit can reach 1 GHz.
