Growth, Optical and Stability Studies of Succinic Aacid Doped KDP NLO Crystal

Potassium dihydrogen phosphate, a well-known nonlinear optical material, has been grown with doping of succinic acid by a slow solvent evaporation technique. The crystals were undergone different characterizationlike X-ray diffraction and infrared spectroscopy analysis for confirmation. Optical transmittance and second harmonic generation efficiency were performed to determine its qualityforthe device. Its frequency conversion efficiency was found to be better than pure KDP. In order to find its mechanical and thermal stability, the crystal was subjected to microhardness testing and thermal analysis. EDAX analysis was done on this grown crystal to confirm the doping elements in KDP.
