Abstract
ABSTRACTWe aimed to investigate the influence potassium tetra thiourea chloride (PTTC) on optical, dielectric and thermal properties of potassium dihydrogen phosphate (KDP) crystals. It was found that by addition of PTTC SHG efficiency has been enhanced. In addition, third order nonlinear properties have been studied by open and close aperture Z-scan technique. The enhanced LDT of grown crystal is found to be 2.08 GW/cm2. The dielectric response of grown crystal results lowers magnitudes. Thermal stability of grown crystal has been studied by TGA, DTA and DSC. The mechanical strength of doped crystals has been investigated by the Vickers microhardness studies and results are discussed.
