Abstract
We introduce the theory of intracavity quasi-phase-matched three-frequency wave interactions in active-nonlinear periodically poled medium, and in particular, self-frequency doubling and halving. The combination of laser oscillation of active ions with nonlinear optical properties of the host material provides an opportunity for creation laser with self- frequency conversion. Quasi-phase-matched second harmonic generation at 0.542 micrometer by self-frequency doubling of fundamental radiation laser radiation at 1.084 micrometer in periodically poled Nd:Mg:LiNbO3 crystal pumping by diode laser at 0.810 micrometer has been observed experimentally.
