Optimizing laser induced nonlinear optical, dielectric and microscopic traits of copper sulfate crystal by glycine for photonic device applications

Abstract

• First comparative article on pure and glycine doped copper sulfate crystal has been reported. • Glycine enhanced optical transmittance of copper sulfate by 8% within 300-698 nm. • Glycine optimized third order nonlinear optical properties of copper sulfate crystal. • Glycine enhanced the laser induced damage threshold energy of copper sulfate by 55 mJ. • Glycine significantly reduced the dielectrics of copper sulfate crystal. Novel investigation reports mono crystal growth of pristine and glycine (C 2 H 5 NO 2 ) doped copper sulfate (CS) by slow solvent evaporation method. The structural analysis has been performed by single crystal X-ray diffraction technique. The presence of various chemical components has been qualitatively established by energy dispersive spectroscopy. The UV-visible spectroscopy has been employed within 200-1000 nm to evaluate the rise in optical transmittance of CS crystal due to glycine. Influence of glycine on third order nonlinear optical response of CS crystal has been examined at 632.8 nm by means of He-Ne laser assisted Z-scan technique. The laser induced surface damage tolerance limit of pure and glycine doped CS crystal has been comparatively investigated at 1064 nm. The impact of glycine and temperature on dielectric traits of CS crystal has been investigated by means of dielectric studies. A comparative etching analysis has been done to investigate surface attributes of pure and glycine doped CS crystal.
