Abstract

A novel mixed alkali hydro-isocyanurate, KLi(HC₃N₃O₃)·2H₂O was first prepared in AOH-BOH-H₃C₃N₃O₃ (A/B = Li/Na/K/Rb/Cs) system via a solvent-drop grinding method. KLi(HC₃N₃O₃)·2H₂O shows a large second harmonic generation response (5.3 × KH₂PO₄) with an ultraviolet cutoff edge of 237 nm. More importantly, the bulk single crystal can be readily grown through water solution technique. Characterization of these crystals indicates that KLi(HC₃N₃O₃)·2H₂O has a high laser damage threshold (LDT) (4.76 GW/cm²) and exhibits a large birefringence (Δ n = 0.186@514 nm), which reduces Type I phase-matching to 246 nm.
