In this paper, Laser ablation of magnesium in Isopropanol using a pulsed copper vapor laser has been reported. The structure, morphology, and optical absorption of the resultant obtained structures were investigated by X-ray powder diffraction, scanning electron microscopy, IR absorption spectroscopy. The obtained results from XRD analysis showed that laser ablation of a magnesiume target in isopropanol forms Mg and MgO structures. The coefficients of linear (α) and nonlinear ( β) absorption, using Nd:YAG laser (λ=532 nm) were calculated by Optical Limiting and open aperture z-scan configuration, respectively. The results showed that nonlinear absorption coefficient is positive and about β=4-10×7/1 mm/watt. The linear absorption coefficient is obtained to be about α=1/27cm-1 for these nanostructures.
