This paper reports the second-order nonlinear optical (NLO) property of NaSb3F10, a potential new NLO material in the infrared region. The compound exhibits a phase-matchable second harmonic generation (SHG) efficiency of about 3.2 times that of KH2PO4 based on the powder SHG measurement. A measurement indicates that its laser damage threshold is as high as about 1.3 GW/cm(2), which is much higher than all those IR NLO crystals reported in the literature. It also shows excellent transparency in the range of 0.25-7.8 mu m with relativity high thermal stability. Single crystal of the size 12x10x8 mm(3) has been grown in aqueous solution by a slow evaporation technique.
