A vacuum-deposited aluminium layer (about 20nm) is sandwiched between two layers of laminated oriented polyporpylene (OPP) film whose thickness varies from 20 to 40 μm. Selected areas of this sealed system were transparentised by the rearrangement of the aluminium layer without breaking the seal or causing damage to the OPP film using a 75 W Q-swiched neodymumdoped yttrium aluminium garnet laser. This paper investigates the effecst of the laser repetition with changes in experimentally produced laser tracks.

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.
