The prepared samples of thin-film by laser ablation method were achieved. Powders of doped cadmium oxide with cobalt of ratios (0,1,3,5,7)wt% were mixed and then compressing by approximately 10 tons. The samples were ablated by using Neodymium-YAG laser with 1000mW and obtained the plasma plume at 0.1mbar pressure and 250oC. Results indicate by using AFM, XRD and FTIR devices that the surface roughness and the size particle decrease with increasing dopants and there are existence stretching bonds of cadmium oxide with cobalt, and have of a multi-cubical polycrystalline .The doping leads to a small decrease in the intensity of the peaks of the cadmium oxide at (200) especially at a concentration of ratio 7%, but it was obtained lowering increase at (111), However, low peaks in most of them due to doping. Absorbance infrared ray have the greatest values of pure cadmium oxide at energies (617.61) (1117.31)(1458.62)(1624.15)(3450) cm -1 and also get a reduction in the absorption peaks as a result to doping with cobalt
