Transparent and homogeneous sodium borophosphate niobium glasses with good optical quality were obtained for Nb2O5 proportion up to 50 mol%. Large NLO second-order susceptibilities, up to not, vert, similar5 pm/V for the highest niobium loading, are generated through an efficient thermal poling process which induces a strong space-charge migration of Na+ cations...
