In material science the word characterization designates to the broad and general process by which a materials structure and properties are enhanced and measured. It is a fundamental process in the field of material science. The advent of new technologies helps to improve the quality of the research by understanding the different behaviors and properties of the materials. In this work we investigated the nanopowder potassium oxalate and its interaction with He-Ne laser are studied. Potassium oxalate is a strong dicarboxylic acid occurring in many plants and vegetables. It is produced in the body by metabolism of glyoxylic acid or ascorbic acid. It is not metabolized but excreted in the urine. It is used as an analytical reagent and general reducing agent. It is an odorless white solid. Now in this study we report the influence of laser heat treatment of nanopowder potassium oxalate. The laser treated potassium oxalate samples are characterized and analyzed by X-ray diffraction, UV-visible absorption, FTIR spectra and SEM. From the X-ray analysis we observed that the laser treated potassium oxalate with the structure of orthorhombic phase structure and the crystalline size in the range of 53 nm to 59 nm. The UV-Visible spectrum also confirms the presence of potassium oxalate nanoparticles with the average band gap energy 5.3 -5.7 eV. FTIR confirms the presence of potassium oxalate nanoparticles with various groups. The average particle size observed in both SEM and XRD measurements are nearly equal values.
