Picosecond Laser Pulse Interactions with Metallic and Semiconductor Surfaces.
Abstract
Picosecond heating and cooling experiments on silicon, GaAs, graphite and metal surfaces are reported. The surfaces are probed by a picosecond pulse, following the heating pulse, as a function of wavelength, time delay and energy fluence. Picosecond laser-induced transformations of modulated metal energy fluence. Picosecond laser-induced transformations of modulated metal films extend the glass formation range. New glassy alloys have been formed. Keywords include: Laser-materials interactions, Picosecond pulses, Metallic and semiconductor surfaces, Phase transitions, and Ultrafast heating and cooling.
