Abstract
Abstract Methyl 4-aminobenzoate (MAB) single crystal has been grown by Bridgman-Stockbarger method with suitable temperature gradient. Unit cell parameters of MAB single crystal have been determined from X-ray diffraction analysis. The different types of vibration mode were analysed through the FTIR spectral study. UV–Visible NIR spectrum shows that the grown crystal possesses good optical transmittance of about 80% in the infrared region. The obtained transmittance data have been used to evaluate the various optical properties such as optical absorption coefficient, bandgap, refractive index and extinction coefficient of the grown crystal. The detailed thermal properties of the MAB single crystal have been examined through the simultaneous thermogravimetric and differential thermal analyses. The laser damage threshold analysis reveals the good resistance of MAB single crystal to high power laser radiation compared to several known nonlinear optical crystals. Third-order nonlinear behavior of MAB crystal was analysed by open and closed aperture Z-scan analysis.
