  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.
