•The UV spectral analysis of LHFFAM attest its suitability in optical applications.•The Photoluminescence spectral study disclosed the electron excitation of LHFFAM.•SHG efficiency is 1.70 times of standard KDP.•Z-Scan technique revealed the third order nonlinearities in LHFFAM. L-histidinium Fumarate Fumaric acid Monohydrate (LHFFAM), an organic nonlinear optical single crystal[C14H19N3O11], has been synthesized and grown using aqueous solution by slow evaporation technique at room temperature. Crystal structure details were obtained from single crystal XRD. The coordination of functional groups was identified in the grown crystal by FTIR analysis. The UV-absorption studies evince the transparent nature of the crystal is in the visible region and the optical band gap energy Eg was evaluated. The TG/DSC analyses confirm the thermal stability for the as-grown crystal. The Vickers microhardness test was carried out on the grown crystals and there by Vickers hardness number (Hv), work hardening coefficient (n), yield strength (σy), stiffness constant C11 were evaluated. The dielectric behaviour of LHFFAM has been determined in the frequency range 50 Hz to 5 MHz at various temperatures. Kurtz-Perry and Z-scan techniques were performed for the acentric crystal LHFFAM which highlighted good nonlinear response and hence proves it appropriate for frequency conversion process and photonic device fabrications. Figure shows (a) Closed aperture (b) Open aperture and (c) Ratio of the closed-to-open Z-scan traces of L-histidinium Fumarate Fumaric acid Monohydrate (LHFFAM). [Display omitted]
