Experimental And Theoretical Studies

ABSTRACTWe have performed experimental and theoretical studies of the origins of anisotropic second harmonic generation observed in reflection from (111) and (100) faces of crystal Ge and Si. Results, using 25 psec and 20 nsec 1.06 and 0.53 μm pump beams allow us to conclude that induced plasmas have no role in the effect and that the mechanism for the nonlinearity is associated with quiescent surface dipolar or bulk quadrupolar effects. Dispersion in the anisotropic behaviour is presented and the application of anisotropic harmonic generation to structural determinations of Si and Ge during laser annealing will be discussed.

Micro Structuring

Laser interference micro-structuring is a relatively efficient and cost-effective technique for fabricating periodical micro-nano-structuring surfaces. The direct fabrication of sub-micron sized dot array on silicon was performed by four interfering nanosecond laser beams with a diffractive beam splitter. The mechanism to form the dot array was analyzed and it was found that the obtained conical dot array had a negative shape of the interference pattern of four laser beams. A second-order peak between two first-order peaks also occurred due to the liquid-solid expansion.
