A practical review of the use of laser ablation lor the deposition of thin films of oxide superconductors and metals is presented. Details of the design and operation of a laser ablation deposition system are discussed, together with the influence of operating parameters such as laser wavelength and power density on the film growth, with the a:m of assisting the researcher oeginning to use andl...
PURPOSE To explore the tissue ablation properties of pulsed 266-nm and 213-nm laser radiation in porcine retina and the potential for 213-nm laser radiation to cut through human trabecular meshwork. METHODS Segments of porcine retinas were used, and localized areas of tissue were exposed to 266-nm or 213-nm laser. Human trabecular meshwork from donor eyes was also ablated using pulsed 213-nm ...

Conference Item How to cite: Sestak, Stephen; Watson, Jonathan S.; Sherlock, Sarah; Greenwood, Paul F. and Fuentes, David (2008). Is UV laser ablation a suitable tool for geochemical analysis of organic rich source materials? In: 15th Australian Organic Geochemistry Conference, 8-12 September, Adelaide.
La0.67Ca0.33MnO3 thin films were epitaxially grown on miscut MgO(001) substrates by pulsed laser ablation. Electrical transport properties were studied by using an ultra high vacuum, four-probe STM system at different temperatures. Anomalous resistivity behavior and metal-insulator transition temperatures were found, both of which are highly dependent upon the miscut angle (1, 3, and 5°). These...
We characterize spatial dispersion in longitudinally invariant drawn metamaterials with a magnetic response at terahertz frequencies, whereby a change in the angle of the incident field produces a shift in the resonant frequency. We present a simple analytical model to predict this shift. We also demonstrate that the spatial dispersion is eliminated by breaking the longitudinal invariance using...
