The material used in this study is Nylon 6, all set in square sheet thin films samples of 100 cm2 with 15 μm thickness. Our optical setup is based on deliver the laser beam all the way through the work piece using X-Y scanning mirrors mounted on galvo-like motors and an f-theta lens with 15 cm focal length and 50 μm focal spot sizes. The fluence (laser energy) is controlled by a pulse signal generator having the possibility to change the pulse repetition rate (PRR) and the pulse width (PW) of the laser beam. Our results show the best weld seam for scanning speeds of 20mm/s and the pulsed laser beam with 2 KHz PRR and 80 μs for the PW time. The scanning speed and trajectory for the welding process are all controlled by a computer in which one can modify the weld parameters. The irradiance at the focal point is set to 1.146 MW/cm2 while the average optical power was set to 22.5W. Our experimental parameters are previously modeled by using COMSOL Multiphysics software were the laser heat source is modeled on the selected material. This model is based on the heat transfer partial differential equation and solved by finite elements procedure. Model results show a perfect agreement with the experiments. Finally, the quality of the welded seam is studied by means of sealed tight and share force critical mechanical test.","PeriodicalId":359625,"journal":{"name":"Symposium on Optics in Industry","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130969480","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}

From 10 founding members, SECPhO no incorporates over 40 members, which is nearly 40% of the optics industry in the region. From the beginning of operations the cluster has focused on three strategic challenges: R&D+i and Productivity, Visibility and Internationalization, and Betterment and Retention of Talent. A brief summary of the clusters activities is given. In this article, the focus will be on R&D and innovation, through industry driven collaborative initiatives and the tools and actions that lead to successful partnerships. Topics discussed in this work are will be a cluster's role in promoting strategic change, the value chain approach to partnerships, international collaboration in projects and specific cluster activities. Some practical examples of initiatives relating to effective collaboration are described, focusing on one of the mayor challenges of our time: the greening of the planet. Examples will be addressed in smart cities, efficient LASER applications and lightweight optical sensors for civil security. In all cases the collaboration between the public and private sectors is shown.","PeriodicalId":359625,"journal":{"name":"Symposium on Optics in Industry","volume":"59 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116521043","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 Judd-Ofelt (JO) intensity parameters (Ωt), the spontaneous emission probabilities, the branching ratios and the radiative lifetimes for each observed Er3+-ion levels were determined. The stimulated emission cross section, the fluorescence full width at half maximum (FWHM), Δλeff, the Δλeff x σe factor, and the gain spectra of the main Er3+-ion lasing emission (4I13/2→4I15/2) are obtained after exciting the glass sample at 532 nm (4I15/2 →4S3/2 ). The absorption cross section of the 4I15/2→4I13/2 transition of the Er3+-ions was also obtained from absorption spectrum of the new glass. The results are compared with those reported for other Er3+-doped oxide glasses pumped at various excitation wavelengths, indicating the new Er3+- doped boro-tellurite glass has potential properties as an optical amplifier in the C-telecommunication window (1.53 μm) and a IR tunable laser. Additionally a radiative energy transfer from the glass host to the Er3+-ions was observed at 520 nm by exciting the glass sample at 466 nm into the Er3+-ion dark region.","PeriodicalId":359625,"journal":{"name":"Symposium on Optics in Industry","volume":"115 19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126372218","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}
