Abstract
Several experiments showed that nickel and copper salts are decomposed to oxides by irradiation with a continuous wave CO2 laser. The proces ses are characterized by an extremely high heating rate which develops within the impact region of the laser beam with the substrate. The sa lts were also decomposed under controlled heating conditions. A differ ence was noticed concerning the size and isotropy of final crystallite s obtained by laser irradiation as compared with thermal heating. The magnitude of this difference seems to be related to the laser quanta a bsorptivity of the salts.
