Abstract: Nowadays the liquid lasers play as an important tool and are used in many applications such as spectroscopy, medicine. This research was carried out to study the possibility of using the Nigella Sativa oil as a laser gain medium and the chemical composites. For this purpose absorption spectrum was carried out which ranged from 600 to 680 nm, and emission spectrum ranged from 650 nm to 700 nm, this emission range includes the laser wavelengths that used to treat wound healing and wrinkles and 690 nm treat in photodynamic therapy. Totally 7 compounds were identified based on their molecular mass, retention time and peak values, among them, the highest amount was obtained for 9-octadecenoic acid (48.16%) and low peak value was tetradecanoic acid (Myristic acid), isopropyl ester (0.52).
