Pr3+-doped Y2O3 nanocrystals embedded in Y2O3 thin films as a sandwich-like structure prepared by pulsed laser deposition

Enhanced magnetoresistance in Ag-doped granular La2Õ3Sr1Õ3MnO3 thin films prepared by dual-beam pulsed-laser deposition

In this article, we report our investigations on the doping effect metallic Ag on the intergrain magnetoresistance phenomenon. La2/3Sr1/3MnO3 ~LSMO! thin films with Ag doping were prepared on ~001! LaAlO3 at different substrate temperatures (Ts) by the dual-beam pulsed-laser deposition technique. Grown at Ts5750 °C, the films are perfectly epitaxial with their c axis perpendicular to the film s...

Laser Performance of Yb-doped-Garnet Thin Films Grown by Pulsed Laser Deposition

Growth and planar-waveguide laser (PWL) performance of garnet-crystal-films are reported. Demonstration of 70% slope efficiency with >16.5W realized with Yb:YAG, along with the first Yb:GGG and Yb:YGG PWLs. Thickness and performance scaling will be discussed. OCIS codes: (310.0310) Thin films; (220.4610) Optical fabrication; (230.7390) Waveguides, planar; (130.0130) Integrated optics; (140.3380...

Pulsed Laser Deposition of Hydroxyapatite Thin Films

Pulsed laser deposition of VO2 thin films

High quality vanadium dioxide ~VO2! thin films have been successfully deposited by pulsed laser deposition without postannealing on ~0001! and ~101̄0! sapphire substrates. X-ray diffraction reveals that the films are highly oriented with ~010! planes parallel to the surface of the substrate. VO2 thin films on ~0001! and ~101̄0! substrates show semiconductor to metal transistions with electrical r...
