Synthesis and Evaluation of New Semi-Organic Non-Linear Optical L-Glutamic Acid Manganese Chloride (LGAMC) Crystal for Frequency Conversion Applications

In this Work, L-Glutamic acid manganese chloride (LGAMC) semi-organic nonlinear optical crystal has been grown by slow evaporation technique. Crystal structure and essential functional groups of LGAMC crystal were confirmed by single crystal XRD and FTIR analyses. Thermal stability and surface trait were determined by using TG/DTand SEM analyses. Linear optical studies revealed the lower cut-off wavelength at 244 nm in transparency UV-Visible region. Mechanical behavior of the crystal was analyzed by microhardness test which indicates that the hard category material. From photoluminescence spectrum, a sharp emission peak was observed at 532 nm which demonstrates that the grown crystal has good nonlinear optical behavior. The SHG efficiency of LGAMC crystal was found to be 1.3 times superior than well-known reference KDP crystal.
