Changes of the acoustical pulse form of longitudinal and shear ultrasonic waves, excited by the optical-acoustical sources of circular form from polar angle are investigated. It has been stated that the form of gaussian pulse of shear ultrasonic waves is sufficiently transformed under the increase of the polar angle; the change of the form of longitudinal ultrasonic waves pulse is more significant. It has been shown that acoustical pulse amplitude is determined by the diffraction function of the longitudinal and shear ultrasonic waves on the circular form opening.
