Abstract Τhe objective of the thesis is to study the interaction of ultrashort and intense laser pulses with metallic surfaces, i.e., multiphoton photoelectric effects, harmonic generation and ellectron relaxation phenomena. For this purpose various pulsed laser systems are utilized with warelenght from UV to IR and pulse duration from 100fs- 20ns as well as and special treated metal surfaces. Using time-resolved, energy-resolved and intensity dependent experiments, it is proved that thermal non-equilibrium phenomena between electrons and lattice induced by the ultrashort laser pulses, as well as electrons relaxation phenomena play the most important role in the interaction, i.e., in the multiphoton photoelectric effect and in the harmonic generation. New theoretical models are represented that explain satisfactory the experimental results and generally the interaction
