Contrast image formation based on thermodynamic approach and surface laser oxidation process for optoelectronic read-out system

A pulsed fiber laser with the wavelength 1.06 µm was used to treat titanium nitride film deposited on beryllium substrates in the air with intensities below an ablation threshold to provide oxide formation. Laser oxidation results were predicted by the chemical thermodynamic method and confirmed by experimental techniques (X-ray diffraction). The developed technology of contrast image formation is intended to be used for optoelectronic read-out system.
