Theoretical Modeling of Laser-Stimulated Nanostructures

摘要

1 Introduction The structure of the surface and its physics and chemical properties are important factors influencing the processes occurring at the interface. By changing the structure and these properties of the surface, one can control these processes. The lasers with femtosecond pulses have become widely used for the modification of the surface. The efficiency of practical use of femtosecond laser pulses is due to the very short pulse length (5-500 fs), high peak power in the pulse (up to 10~(15) W), and when focused, high laser intensity (10~(11)-10~(22) W/cm~2). Powerful parameters of femtosecond laser pulses are actively used to solve various fundamental and applied problems.
