Abstract :
Summary form only given. Many fundamental processes in physics, such as heat transport and phase transitions in solids involve movement of the constituent atoms. Such changes cannot be directly measured with visible light and occur transiently on time-scales comparable with the natural oscillation periods of atoms (femtoseconds to picoseconds). In this paper, we present experiments on crystalline semiconductors irradiated with short visible pulses in two fluence regimes.
