Abstract Ultrafast (or ultrashort) pulsed laser ablation of biological tissue has drawn much attention due to the minimal collateral damage caused by laser irradiation. Many clinical applications of ultrafast laser ablation have been proposed, including ophthalmology, dentistry, and neurosurgery (Kim et al., 1998). During ultrafast laser interaction with biological tissues, which are dielectric materials, multiphonon absorption occurs which enhances the absorption of the laser beam in tissue. The tissue can then be heated rapidly to a high temperature, causing evaporation and tissue removal.

Deposition Parameters

Pulsed-laser ablation has been widely used to produce high-quality thin films of YBa2Cu3O7-δ on a range of substrate materials. The nonequilibrium nature of the process allows congruent deposition of oxides with complex stoichiometrics. In the high power density regime produced by the UV excimer lasers the ablated species includes a mixture of neutral atoms, molecules and ions. All these species play an important role in thin-film deposition. However, changes in the deposition parameters have been shown to affect the microstructure of thin YBa2Cu3O7-δ films. The formation of metastable configurations is possible because at the low substrate temperatures used, only shortrange rearrangement on the substrate surface can occur. The parameters associated directly with the laser ablation process, those determining the nature of the process, e g. thermal or nonthermal volatilization, have been classified as ‘primary parameters'. Other parameters may also affect the microstructure of the thin film. In this paper, the effects of these ‘secondary parameters' on the microstructure of YBa2Cu3O7-δ films will be discussed. Examples of 'secondary parameters' include the substrate temperature and the oxygen partial pressure during deposition.

While doping is crucial for numerous technological applications, its control remains difficult especially when the material is reduced down to the nanometric scale. We suggest a new way to dope nanoparticles using laser ablation in liquids.
