High quality K3B6O10Br single crystal with size up to 18 mm × 18 mm × 10 mm was obtained via top-seeded solution growth (TSSG) method using KF · 2H2O-PbO binary fluxes. The experiments show that the UV transmission cut off of K3B6O10Br is about 210 nm. Nonlinear optical measurements demonstrate that the material has second harmonic generation (SHG) properties, with efficiency approximately three times that of KH2PO4. The refractive index was test and fit the Sellmeier equation. SHG experiment indicates that the K3B6O10Br can achieve 532 nm and 355 nm frequency-doubled wavelength. The damage threshold, hardness and deliquescence were reported.
