Crystals of potassium dihydrogen phosphate (KDP) doped with boron has been grown by slow solvent evaporation method at room temperature. The presence of boron is confirmed by EDAX. The presence of the functional groups has been identified by Fourier transform infrared spectrum. The grown crystal was characterized by powder and single-crystal X-ray diffraction studies. The optical nature of the grown crystal is analyzed using the UV-Vis spectrum. The variation of photocurrent (Ip) and dark current (Id) with applied field were determined. The SHG efficiency of boron doped KDP is higher than the pure KDP
