Intracavity self-frequency conversion in periodically poled active nonlinear Nd:Mg:LiNbO 3 crystal

Alexey A. Novikov, G D Laptev, Ivan V. Shutov

Abstract

We introduce the results of the study of quasi-phase matched processes of self-frequency conversion in periodically poled active nonlinear crystals. The processes of self-frequency doubling and self-frequency summing have been experimentally realized and studied in periodically poled Nd:Mg:LiNbO3 crystals in CW and Q-switched regimes. The theory of self-frequency conversion has developed. The results of theory are in good agreement with experiments.
