| Abstract: | Nd: KGd(WO4)2 thin films were deposited by KrF laser ablation on MgO, YAP, YAG and Si substrates at temperatures up to 800 °C. Film crystallinity,
morphology, stoichiometry (WDX, RBS and PIXE), excitation spectra, fluorescence, refractive index and waveguiding properties
were studied in connection with deposition conditions. The best films were crystalline and exhibited losses of approximately
5 dB cm-1 at a wavelength of 633 nm.
