  • Abstract
    A method for noninterference sampling of high-power CO2laser beams is described. The technique employs an ultrasonic diffraction grating generated in the air path across a laser beam. A very small fraction ( \\sim10^{-7} ) of the main beam is diffracted through a small angle ( \\sim2\\deg ) on either side. Profiles of Gaussian and "donut" modes from low-power CO2lasers were obtained with the acoustic beam splitter.
