Abstract Large size and high quality single crystals GdCa4O(BO3)3 have been grown from platinum crucible under air atmosphere by the conventional rf-heating Czochralski method. The crystal growth conditions, growth habits, and transmission spectra were investigated. The crystal is transparent in the visible and near-infrared region (320-2600nm). It has a good second harmonic generation phase-matching condition. The phase-matching experiment result is well consistent with the theoretical one. The frequency-doubling efficiency is 26.7% in the phase-matching angles θ = 45o and ø = 45.1o direction.
