Abstract

Abstract Crystals made of RbNbB 2 O 6 (RNB) crystal or any of the XYB 2 O 6 family members (where X═Li, Na, K, Rb, Cs, Tl; Y═Nb, Ta, V, Sb) or related combinations in solid solutions are useful as Nonlinear Optical Devices. These crystals can produce nonlinear optical conversion effects including second harmonic generation (SHG), sum frequency generation (SFG), differential frequency generation (DFG) and optical parametric amplification (OPA). These nonlinear conversions operate on both bulk crystals and thin films including waveguide devices. RNB crystals have the advantage over prior art crystals for having better UV (ultra-violet) transparency on the order of 270 nm.
