Growth and Characterization of Pure and Fe3+ Doped KHP Nonlinear Optical Single Crystals

P. Rajasekar ^[2] | K. Thamizharasan

Abstract: Pure and iron doped single crystals of Potassium Hydrogen Phthalate were grown successfully by slow evaporation method. The concentration of dopant in the mother solution was 1 mol % and 1.5 mol %. There is a drastic change in the morphology due to variation in doping rates which is also reflected in the X-ray diffraction data. The Fourier Transform infrared spectroscopy study confirms the incorporation of metal ions into Potassium Hydrogen Phthalate crystal. The thermal study indicates the dissociating nature of the crystal. The nonlinear optical property of the grown crystal has been confirmed by Kurtz-powder second harmonic generation test. The dopant of 1 mol % and 1.5 mol % shows higher second harmonic generation result than pure Potassium Hydrogen Phthalate.
