Three different compounds, cubic Gd₂O₃, orthorhombic GdGaO_3, and cubic Gd₃Ga₅O₁₂ doped with Pr³⁺ ions were fabricated as waveguiding films by pulsed laser deposition from the same target material, Pr³⁺ doped Gd₃Ga₅O₁₂ (Pr:GGG) single crystal. All of them were deposited at the same substrate temperature of 800 °C. The different crystalline phases obtained depend only on the ambient oxygen pressure and the substrate type (YAG or YAP single crystals). The structural and texture properties of the films were analyzed by x-ray diffraction. Pr³⁺ fluorescence properties were found to be similar to those of the bulk crystals. The refractive indices and waveguiding properties of the films were determined. The fluorescence properties of Pr³⁺ doping ions and the refractive index of the film are presented. The oriented crystalline Pr:GdGaO₃ and Pr:GGG films show waveguiding propagation with attenuation around 2.5 and 1 dB/cm, respectively.
