Using KrF laser ablation the fabrication of Yb:YAG, and Cr:YAG planar waveguides as well as nonlinear Co:BaTiO3 waveguide has been carried out. The waveguide structure was fabricated by deposition of a rare-earth-doped YAG layer on an undoped substrate. The optical waveguide was characterized by optical absorption spectra, photoluminescence spectral intensity, optical propagation loss, and valence state by XPS. Co:BaTiO3 nonlinear optical, thin films have been fabricated with good quality using a new hybrid process of two-target pulsed laser deposition and in-situ pulsed laser annealing. Epitaxial Co:BaTiO3 films with Co/Ti concentrations of up to 5% were achieved by this method. Particles on the growing film were almost eliminated by in-situ laser annealing. Cobalt dopant concentrations were easily adjusted and controlled.
