- Single crystals of undoped and rubidium chloride doped lithium sulfate were grown by solution method with slow evaporation technique. The reactants used are AR grade lithium sulfate and rubidium chloride and double distilled water was used as the solvent. Colourless, transparent and non-hygroscopic crystals were harvested after a growth period of 35 days. The crystal structure was found by XRD studies. Second order NLO studies were carried out by Kurtz-Perry powder technique. Third order NLO studies were done on the grown crystals by Z-scan technique and nonlinear optical refractive index, nonlinear absorption coefficient and nonlinear susceptibility were determined. The dielectric constant and dielectric loss of the samples have been found at different frequencies and temperatures and the results are discussed.
