Maximum intensity determination of beam waist in BBO optical nonlinear crystal using single harmonic generation

Nonlinear optics is a branch of that explains the nonlinear response atoms and molecules to field light radiation. There difficulty in cutting crystals shapes commensurate with their optical properties, thus it was significant determine descriptive shape crystal properties based on its optic be ideal use. The problem determining length give best output power still under study research one most important topics. In our research, computational method mathematical relationships used estimate BBO I-type, which gives power, by manipulating location scattering middle crystal. It found width 3mm height 7mm. comparison these results previous literatures gave great match, confirms correctness computations reliability method.
