Crystals made of RbNbB206 (RNB) crystal or any of the XYB206 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 conversation 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 better UV (ultra-vio-let) transparency on the order of 270nm.
