Picosecond Laser Pulse Interactions with Metallic and Semiconducting Surfaces.

摘要

Pump-probe, ellipsometric, and streak camera measurements of the reflectivity following picosecond pulse irradiation of semiconductor, graphite, layered compound, and metal surface are reported. Overheating of crystal and liquid are analyzed. Crystallization of metals is shown to be collision-limited. Kinetic preference for formation of isotropic, small unit cell crystals is established.
