Nonlinear optical, optical limiting and dielectric properties of organic cyclohexylammonium acetate single crystal

We report the growth and nonlinear optical properties of cyclohexylammonium acetate (CYHAC) crystal. The functional groups and crystal structure were determined using FT-IR analyses and single crystal XRD (293 K). UV-Vis-NIR measures the cutoff wavelength (254 nm) and optical band gap (5.17 eV) of CYHAC crystal. TG-DSC spectrum shows the melting point (161 °C) and decomposition of the compound. Activation energy was calculated from dielectric studies as a function of frequency at different temperatures. Laser damage threshold of CYHAC is 5.23 GW/cm2. Nonlinear optical parameters were calculated using Z-Scan technique for this material and its optical limiting behavior were also tested, the value of limiting threshold and clamping output are 24.3 mW and 7.1 mW respectively.
