GHz Frequency Optical Pump-Probe (GFOPP) Metrology Tool for High Sensitivity Measurements of Acoustic Dissipation and Elastic Constants

Abstract

The goal of the project was to purchase components and construct a non-contact metrology tool for studying GHz frequency acoustics of a wide range of bulk and thin film materials. Our GHz frequency optical pump probe (GFOPP) metrology tool will enable experiments on the physics of acoustic dissipation in materials at frequencies comparable to thermal phonon relaxation rates.
