An acoustic holographic lens structure is described for generating thermoelastic waves from the energy of absorbed laser excitation. The structure uses a large area optically absorbing surface to permit the megahertz ultrasound to be focused for nondestructive evaluation applications. Experimental results for the spatial distribution of 10-MHz ultrasonic waves obtained from the hologram are presented.
