The nonlinear absorption coefficient and reverse saturable absorption on optical limiting threshold behavior was exhibited by 1-((E)-(2,5-dichlorophenylimino)methyl)naphthalen-2-ol (E25DCM) under the Nd: YAG nanosecond laser (532 nm, 9 ns, and 10 Hz) excitation. E25DCM crystal was grown by the slow evaporation technique at ambient temperature. The crystal structure was identified using the single crystal X-Ray diffraction analysis E25DCM belongs to Orthorhombic system with space group P2 1 2 1 2 1 . The Fourier Transform Infrared Spectroscopy, 1 H-NMR Spectroscopy, and 13 C-NMR Spectroscopy have all been well correlated with E25DCM structure. The thermal behavior indicates that E25DCM stable up to 160 °C. Surface analysis explains the irregular arrangement of E25DCM. The UV–Visible spectrum showed the absorption of E25DCM at 325 and 340 nm, and moderate transmittance is observed at the level of 62%. The optical band gap, which results in blue emission, is shown in the fluorescence spectrum at a value of 3.97 eV. The efficiency of crystal has significantly improved in the Second Harmonic Generation (SHG).Based on the Nonlinear absorption coefficient and optical limiting value of E25DCM, this crystal can be classified as an excellent NLO material and also a best contender for the use in developed laser safety devices.
