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.
A special place for the use of femtosecond laser pulses is assigned to the technological field, which is associated with micro-processing, as well as nano- and microstructuring of solid-state materials. Surface treatment of solid materials by femtosecond
laser is an efficient and highly co-productive technology (up to 500 m/s). It allows
to create a huge variety of modified surfaces. Due to the effect of nonlinear absorption of powerful femtosecond laser pulses, not only surface but also 3D processing
of transparent materials for laser radiation of materials is possible. With the help
of femtosecond laser pulse effects, one can process almost any material including
metals, semiconductors, dielectrics, and various alloys, including both massive and
multilayer thin film structures (layer thicknesses 5–100 nm).
However, it is clear that the result of treatment depends on the characteristics of
the irradiated material (Fig. 1). An important role is played by the environment in
which the irradiation process takes place (Fig. 2). Also significant is the duration
and, accordingly, the impulse power (Fig. 3).
