Experimental study of nonlinear optical (NLO) property of 25 kHz ultrasonic assisted crystallized zwitterion L-glycine (USALG) and non-assisted crystallized zwitterion L-glycine (LG) are reported. Good-quality single crystals of LG and USALG were successfully grown by a slow evaporation technique at room temperature. They were characterized by powder X-ray diffraction technique and both crystals were found to crystallize in the monoclinic system. The ultrasonic (US) assisted crystal possessed better transparency and crystalline perfection. The electrolytic conductivity (κ) of aqueous solutions of the crystals was measured using a conductivity meter at room temperature, and USALG exhibited high electrolytic conductivity. The second harmonic generation (SHG) efficiency was evaluated by the Kurtz and Perry method, and USALG was found to be 1.53 times more efficient than standard potassium di-hydrogen phosphate (KDP). The experimental result showed that USALG exhibited good second order nonlinear optical property.
