Abstract

A theoretical model for determine the optimal focusing parameter for second harmonic generation (SHG) process in a polycrystalline nonlinear medium has been constructed. Theoretical calculations were confirmed by an experiment to obtain SHG at a wavelength of 968nm in a zinc selenide polycrystal using a thulium laser.

期刊介绍： This journal is devoted to the rapidly advancing research and development in the field of nonlinear interactions of light with matter. Topics of interest include, but are not limited to, nonlinear optical materials, metamaterials and plasmonics, nano-photonic structures, stimulated scatterings, harmonic generations, wave mixing, real time holography, guided waves and solitons, bistabilities, instabilities and nonlinear dynamics, and their applications in laser and coherent lightwave amplification, guiding, switching, modulation, communication and information processing. Original papers, comprehensive reviews and rapid communications reporting original theories and observations are sought for in these and related areas. This journal will also publish proceedings of important international meetings and workshops. It is intended for graduate students, scientists and researchers in academic, industrial and government research institutions.
