Abstract

The waveguiding films of YAlO₃ and Y₃Al₅O₁₂ doped by Nd were directly deposited on (0001) and (1102) sapphire substrates by a pulse laser ablation. The waveguiding properties were measured by m-line technique. The increase of the films refractive index by (Delta) n equals 8 X 10^-3 was observed with the change of dopand Nd concentration of 0.16 at.%. Waveguiding losses lower than 1 dB/cm have been demonstrated at 1.06 micrometers wavelength. The nonuniformity of the thickness was determined by prism-film coupling method. Plasma plume distribution as cos²⁸((theta) ) was calculated.
