Using a slow evaporation process, a crystal of L-cysteine hydrochloride monohydrate magnesium sulphate (LCHMS) was produced at room temperature. The generated LCHMS crystal’s presence in the monoclinic system with the space group C2/c and cell dimensions a = 10.10 Å, b = 7.22 Å, c = 24.44 Å and α = γ = 90°, β = 98.13° is confirmed by single-crystal X-ray diffraction analysis. Using infrared spectral analyses, the functional groups contained in the crystal were explored. Calculated from the UV–Vis–NIR spectral data, the lower cut-off wavelength, optical bandgap, and Urbach energy are determined to be 233 nm, 5.32 eV, and 0.31304, respectively. The crystal has a higher laser damage threshold of 17.34 GW/cm² and an emission peak in the blue area. The frequency changes in the dielectric profile were used to calculate the electrical characteristics of the formed crystal. The effect of compounds on the surface morphology of LCHMS crystals was studied using SEM. To find out about the elements that are present in crystals, an EDAX analysis was employed. According to the hardness research, the material has Meyer’s index of 2.5, indicating that it falls into the soft crystal group. Using a conventional Z-scan technique, the optical limiting threshold (3.52 × 10¹² W/m²) action and optical nonlinearity nonlinear absorption coefficient (0.9 × 10⁻¹⁰ m/W) of the formed crystal were precisely determined.
