Development and Evaluation of an Efficient Second Order Non-Linear Optical Single Crystal - 2-(3-Aminopyridinium-1-yl)-3-carboxyproponate monohydrate

slow evaporation solution approach was used to create high-quality single crystals of 2-(3-aminopyridinium-1-yl)-3carboxyproponate monohydrate (3ACPM). The single crystal X-ray diffraction was used to determine the crystal system and lattice characteristics. Software called Krystal Shaper was used to mimic the morphology of the 3ACPM. To evaluate the optical transmittance, UVvis spectral analysis was used. The Nd:YAG laser was used to assess the laser-induced surface damage threshold (LISDT) of 3ACPM single crystal. The presence of second harmonic generation (SHG) was evaluated using the Kurtz-Perry powder method.
