Recently simultaneous generation of continuous-wave visible laser light in the three fundamental colors has been experimentally demonstrated in Nd3+-doped LiNbO3 and Sr0.6Ba0.4(NbO3)2 by quasi-phase matching intracavity self-frequency conversion. In this work, we report the modelization of RGB lasers operating under similar experimental conditions but designed in the simplest quasi-periodically poled ferroelectric form by using the Fourier Transform technique. The aim of this work is to analyse the possibility of controlling the three laser intensities in an independent and novel way by means of the linear electrooptic (Pockels) effect in these non-linear materials. Our results suggest that the application of electrooptic effect for this purpose, according to our proposed scheme, is better adapted to Sr0.6Ba0.4(NbO3)2 than to Nd3+-doped LiNbO3.
