Abstract
The effect of NaCl, KCl and SrCl2 doping on the crystal structure, optical transmission, and second harmonic generation (SHG) efficiency of potassium dihydrogen phosphate (KDP) crystals is investigated. Single crystals of pure NaCl, KCl and SrCl2 doped KDP were grown by solution growth technique from aqueous solutions. The crystal structure was studied by powder X-ray diffraction. Doped crystals possess higher optical transparency than pure KDP crystals. The SHG efficiency of doped crystals was found more than pure KDP crystal. The grown crystals were subjected to the photoluminescence, atomic absorption and FT-IR spectroscopic study.
Keywords: Crystal growth, X-ray diffraction, nonlinear optics, FT-IR spectroscopy, optical transmission, second harmonic generation
