Third Order Nonlinear Optical Properties of Urea Salicylic Acid for Phot Ionic Applications
The single crystal of urea salicylic acid was generated in this study utilising a slow evaporation approach using a mixture of water and ethanol as the solvent. Using a combined solvent of ethanol and water in an equal ratio, slow evaporation was employed to form an organic nonlinear optical crystal of urea salicylic acid. A single X-ray diffraction analysis was used to determine the lattice characteristics of the urea salicylic acid crystal. The optical transmittance investigation demonstrated the urea-salicylic acid’s good transmission window and appropriateness for optical applications. The Z-scan approach with a He-Ne laser at evaluated the nonI linear refractive index, absorption coefficient, and third order susceptibility. Two photon absorption and self-defocussing performance are demonstrated by the generated urea salicylic acid crystal. The self-defocusing nature and two photon absorption process of the generated urea salicylic acid crystal were confirmed using the Z-scan method. As a result, urea salicylic acid crystals are a good choice for optoelectronic applications.
