Abstract :
A method for noninterference sampling of high-power CO2 laser beams is described. The technique employs an ultrasonic diffraction grating generated in the air path across a laser beam. A very small fraction ( 
) of the main beam is diffracted through a small angle ( 
) on either side. Profiles of Gaussian and "donut" modes from low-power CO2 lasers were obtained with the acoustic beam splitter.
