In this paper, we would like to report on the nanohole fabrication on an aluminum (Al) surface by femtosecond lasers due to near-field enhanced effects. The particle size used experimentally is 450 nm and 820 nm (PS, n=1.59) in diameter. The used laser fluence ranges from the bellow-ablation-threshold fluence to the above-threshold fluence of Al films. The ablation threshold of Al films is 400 mJ/cm2 approximately. The Al films were deposited on the silicon substrate by conventional vacuum evaporation method. Particles were successfully arrayed in an hexagonal closed-packed structure (hep) so that the near-field generates uniformly on each particle","PeriodicalId":354643,"journal":{"name":"CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005.","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129375385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drawback is that each technique implies distinct operation characteristics solving specific problems that cannot correspond to the complexity of diagnostic problems involved in the field of cultural heritage. As such the fragmented applicability obstructs their transfer to the new demanding field of application. Therefore the project objective is to integrate complementary advantages of techniques based on the same fundamental physical principles in one system-device capable to provide the desirable flexibility of function and standardised operation providing a user-friendly on-field transportable system as a universal structural diagnostic tool for cultural heritage applications. Structural diagnostics in art conservation lacks novel alternative tools and it is assumed that this essential advance will allow and promote the wide use of laser diagnostic techniques in art conservation discipline enhancing both fields.
