Paper Abstract

Theoretical and experimental studies the features of parametric generation light in LiNbO3 with non-collinear phase matching from non-collinear angle i23, i.e. angle between pump wave vector and resonant signal wave vector, are presented. It was shown that at the small angle i23<0,3 degrees four nonlinear processes can simultaneously take place: these processes are non-collinear parametric conversion of the 1.0642 micrometers into the signal and an idler waves; second-harmonic generation of the signal; non- collinear difference-frequency mixing of the doubled signal and the idler; parametric conversion of the doubled signal into new pair: the signal and an idler waves. It is shown that the maximum efficiency of non-collinear OPO takes place for tangential phase-matching at (formula available in paper). Spectral broadening of the signal wave of LiNbO3 non-collinear OPO was studied. Theoretically it is shown that the spectral bandwidth of the signal wave depends on the divergence of the signal wave.
