Abstract

An investigation was made of metastable states of overheated metal (mercury) when it s surface was exposed to nanosecond laser pulses. The dynamics of the thermodynamic state of mercury was analyzed on the basis of time-resolved measuring of an acoustic pulse propagating from the surface. The contribution of the vapor pressure was identified and the surface temperature was found as a function of time. The surface temperature was been obtain decrease exponentially with time after laser pulse action and the relaxation time was measured. The possibility of new-dynamic laser techniques of materials modification are discussed.
