Pulsed laser deposition of

Superconductor Science and Technology, 1996
We have investigated the crystallinity of (BTO) thin films on (100)MgO and (100)STO substrates and the (YBCO) buffer on MgO. An ArF excimer laser with a fluence 1.4 to 3.6 per pulse was used of the preparation of BTO films at substrate temperatures in 500 to and oxygen pressures of to Torr. BTO thin films with (001) orientation were grown on (100)

Pulsed laser deposition of active waveguides

Thin Solid Films, 2003
We report on the pulsed laser deposition (PLD )of thin films of chalcogenide and tellurite glasses doped with RE ions. The depositions were performed in vacuum, for chalcogenide films,and in a low oxygen pressure for the tellurite films by using an excimer laser.

Inverse pulsed laser deposition [PDF]

Applied Physics A, 2008
Since the advent of pulsed laser deposition (PLD), several different target-substrate arrangements have been proposed. Besides the most common on-axis PLD, several off-axis geometries were studied, mainly to protect the substrate from the agglomerated species (clusters, droplets, particulates) of the plasma plume, which are detrimental to the ...

Pulsed laser deposition of pseudowollastonite coatings

Biomaterials, 2002
Pseudowollastonite (alpha-CaSiO3) is a bioactive ceramic material that induces direct bone growth. A process to obtain pseudowollastonite coatings that may be applied to implants is described and evaluated in this work. The coatings were first deposited on titanium alloy by laser ablation with a pulsed Nd:YAG laser tripled in frequency.

Pulsed laser deposition with excimer lasers

physica status solidi c, 2008
AbstractProgress in material research and processing industry is fueled by the technique of pulsed laser deposition (PLD). High energy excimer lasers enable this technique since every material is amenable to their high photon energies. Spectral properties, temporal pulse and laser beam parameters of state of the art excimer lasers will be compared with

Pulsed laser deposition: analysis and deposition of SmBaCuO films

Applied Surface Science, 1998
Abstract Composition and time evolution of the gas plume were investigated during a PLD of SmBaCuO thin films. Optical emission spectroscopy was employed for investigating the laser-induced plasma plume. The mean velocity of ions has been estimated to be slower when the experiment is performed in the presence of a buffer gas.

Femtosecond pulsed-laser deposition of BaTiO 3

Applied Physics A: Materials Science & Processing, 2003
The elemental composition and the surface morphology of thin films grown by laser ablation of barium titanate with femtosecond pulses at 620 nm laser wavelength have been systematically studied according to the experimental pulsed-laser deposition parameters : laser energy density, oxygen pressure, substrate temperature, target-substrate distance and ...

Pulsed laser vaporization and deposition

Reviews of Modern Physics, 2000
Photons have many advantages for vaporizing condensed systems, and laser vaporization sources have a flexibility not available with other methods. These sources are applied to making thin films in the well-known technique of pulsed laser deposition (PLD). The vaporized material may be further processed through a pulsed secondary gas, lending the source

Pulsed laser deposition of BaGa2O4

Applied Physics A, 2008
This paper reports the first results obtained on monobarium gallate thin films grown on silicon and platinum coated substrates by pulsed laser deposition. The influence of oxygen background pressure and substrate (or post-annealing) temperature on the film properties was studied.

Pulsed laser deposition of CdWO4

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1997
Abstract Pulsed laser depositions of CdWO4 thin films are carried out in the presence of O2 using targets of CdWO4(010) single crystals and pressed CdO and WO3 powder mixtures. CdWO4(002) peaks are observed on Si(111), CaF2(111), mica(001) and glass substrates by ablating CdWO4(010) single crystals.
