Abstract
A point-source representation for laser-generated ultrasound in an elastic, transversely isotropic half-space is developed. This representation is comprised of a set of boundary conditions that approximates a thermoelastic point source located on the bounding surface of the half-space. An analytical expression representing the displacements for wave propagation along the symmetry axis is given for zinc where the bounding surface is the plane of transverse isotropy. The displacements obtained from theory are compared to experimental wave forms generated in a sample of single crystal zinc.
