Laser excitation of surface acoustic waves pulses in solid state bodies

Features of laser excitation of the pulses of surface acoustic Rayleigh waves in solid state bodies through a prism by a source of radiation of the round form are investigated. It is shown, that at increase in the azimuth angle there is increase in the amplitude and reduction of duration of the ultrasound pulse; at increase in the angle of the prism inclination the amplitude of the acoustic pulse decreases, and the duration increases. It is established, that at increase in the radius of an aperture of the round form the pulse amplitude increases and the duration decreases; with the increase in the factor of absorption of a hypersound the pulse amplitude decreases, and the duration increases.
