摘要：
The results of the optoacoustic study of aluminum states within a temperature range of 3–14 kK and a pressure range of 0.1–4 kbar were considered. These high-energy states were achieved by heating a submicron metal film confined by a transparent dielectric via nanosecond laser pulses with a fluence of up to 11 J/cm2. The dynamics of the temperature, pressure, and reflectivity of aluminum was studied at a nanosecond time resolution.
