ABSTRACTThe properties of plasmas generated by the interaction of a pulsed CO2 laser with several solid evaporation targets were studied and the films deposited from such plasmas were characterized. A large flux (˜ 1014/cm2/s) of ions at high velocities (2 − 10 × 106 cm/s) was measured in these plasmas. ZrO2 thin films deposited by laser-assisted evaporation on room temperature substrates had crystalline-oriented structures. Low optical absorption and high refractive index values (2.15 at 632.8 nm) indicated the stoichiometric and dense nature of these films.

The spectra of refractive index and absorption coefficient in thin films of Ge23.5Pb20S56.5 glassy system were calculated on the base of analysis of transmission spectra. The refractive index has values between 2.0 and 2.6 in the spectral range between 500 nm and 1200 nm. The existence of indirect allowed transitions with energy Eg = 1.70 ± 0.01 eV and phonon energy of wph= 0.11 eV at room temperature was found. For values of the absorption coefficient a < 103см –1 the fundamental absorption edge is described by exponential function known as Urbach-rule. The static structure disorder parameter wo, is equal to 0.06 eV.
