ABSTRACTThe recent status of applications of nonlinear optics to surface science is reviewed. The basic theory of wave mixing on a surface layer, and the possibility of using various nonlinear optical processes for surface probing are briefly discussed. Emphasis is on surface second harmonic generation, which is shown with many illustrations to be a rather unique and versatile tool for surface studies.

In this paper, we present the experimental proof that even for highly nonlinear (NL), such as 2-methyl-4-nitroaniline (MNA), wave mixing has negligible effect on the second-harmonic generation (SHG) using 250 fs fundamental pulses. We explain our experimental results with a simple formalism based on monochromatic plane wave (MPW).
