Second-harmonic generation in poled glasses opens new frontiers in optical material research. Within this context new boro-phosphate glasses of the Ca(PO{sub 3})2-CaB{sub 4}O{sub 7}-Na{sub 2}B{sub 4}O{sub 7}-Nb{sub 2}O{sub 5} system were synthesized and their second-barmonic generation was evaluated after poling treatment. The enhancement of the second-harmonic signal with niobium oxide content is related to the presence of distorted NbO{sub 6} octahedra in the former of the glasses and to the increase in third-order susceptibility. The intensity of the measured second-harmonic signal is not dependent on the amount of sodium (100-1000 ppm) introduced into the glass.
