Abstract

Nonlinear optics : A new borosilicate, Cs₂B₄SiO₉, has been synthesized (see picture). This compound represents a new kind of a boron‐rich borosilicate and shows a 4.6 times stronger powder second‐harmonic generation response relative to KH₂PO₄. In addition, Cs₂B₄SiO₉ has a short UV cutoff edge (below 190 nm).
