Ultrafast Measurement of the Optical Properties of Gold and Nickel during Shock Wave Breakout
Abstract
We have used high-resolution spatial and frequency-domain interferometry to make the first ultrafast measurement of shock-induced changes in the optical properties of thin gold and nickel targets. Measurements with an 800 nm probe wavelength found, in addition to phase shifts caused by surface motion, phase shifts accompanying changes in the optical properties of the materials during shock breakout. Data taken at several angles of incidence allowed the separation of optical from material motion effects, yielding an effective complex index for the shocked material.
