Abstract:

An acoustic beamsplitter operating in air at the Bragg angle has been investigated for use with high-power lasers. The interaction involved an acoustic frequency of 1 MHz and an optical wavelength of 10.6 micrometers. Significant results in characterizing the quality of the acoustic diffraction grating were achieved using an infrared probe method. Design parameters for an optimum system as well as recommendations for intended use are discussed. Author
