Abstract

A specific version of the hat pulse technique as applied to diamond is presented. The conventional heat pulse technique implies generation of acoustic phonons near the surface of a solid and analysis of their propagation in the crystal utilizing a certain phonon-sensitive detector. Generation of phonons is usually achieved with the help of a pulsed laser whose quanta are absorbed at or near the surface either by a metal film deposited onto a sample or by the sample itself. In the case of diamond, the latter version requires a powerful UV source and special optics that present some difficulties.
