This work addresses the issue of fast energy distribution relative to a workpiece when laser material processing. Therefore, available technologies are evaluated by their dynamic by the data transfer rate. This rate is the number of resolvable spots per unit time the system can generate. The idea of beam shaping using the acousto-optic effect shows the highest data transfer rate. This idea was caught up in this thesis and a new technology for laser beam shaping is presented. The innovation of this new technology is the calculation of the signals necessary for the acousto-optic laser beam shaping (AOS). An Iterative-Fourier-Transformation-Algorithm for producing efficient laser beam shaping has been developed within this work. First, the thesis deals with the general features of the AOS-technology: switching rate, maximum applicable laser power and restrictions for the achievable intensity distributions. Moreover, hardware to apply this technology with multi-kW-lasers is commercially available. These characteristics make AOS nearly universally applicable with all kind of laser sources in pulsed and continuous wave (cw) operations.<\/p>","protected":false},"excerpt":{"rendered":"
Im Rahmen der vorliegenden Promotionsarbeit wurden Systeme f\u00fcr die Strahlf\u00fchrung und -formung von Laserstrahlen hinsichtlich ihrer Dynamik anhand der Daten\u00fcbertragungsrate bewertet und verglichen. Die Daten\u00fcbertragungsrate ist die Anzahl an Strukturpunkten pro Zeiteinheit, die mit einem System erzeugt werden kann. Es zeigt sich dabei, dass eine Strahlformung mit akustooptischen Effekt die h\u00f6chsten Daten\u00fcbertragungsraten erm\u00f6glicht und somit […]<\/p>\n","protected":false},"featured_media":2315,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[34],"product_tag":[],"class_list":{"0":"post-1546","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-fau-studien-aus-dem-maschinenbau","7":"has-post-title","8":"has-post-date","9":"has-post-category","10":"has-post-tag","11":"has-post-comment","12":"has-post-author","13":"","15":"first","16":"instock","17":"taxable","18":"shipping-taxable","19":"purchasable","20":"product-type-simple"},"acf":{"autor":"Strau\u00df, Johannes","orcid":"","ror":"","herausgeber":"","orcid_hrsg":"","rorhrsg":"","bearbeiter":"","sonstige_beteiligte_personen":"","untertitel":"","zusatz":"","jahr":"2021","zeitschrift":"","serie":"","serie_name":"","serie_band":"","serie_jahr":"","serie_titel_band":"","vortrage":"","issn":"","isbn":"","isbn13":"978-3-96147-441-7","seiten":"xvi. 113","sonstiges":"","band":373,"auflage":"","opus":"","dspace":"17084","e-isbn_pdf":"978-3-96147-442-4","doi":"https:\/\/doi.org\/10.25593\/978-3-96147-442-4","epub":"","e-isbn_epub":"","doi_epub":"","html":"","e-isbn_html":"","doi_html":"","e-isbn_reader":"","doi_reader":"","digibib":"","urn":"urn:nbn:de:bvb:29-opus4-170847","supplementary_material":"","sprache":["Deutsch"],"ausgabe":"Softcover","suche":" 9783961474417 9783961474424 ","lizenz":"BY-NC-4","bemerkung":""},"builder_content":"","_links":{"self":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product\/1546","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/comments?post=1546"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/media\/2315"}],"wp:attachment":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/media?parent=1546"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product_brand?post=1546"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product_cat?post=1546"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product_tag?post=1546"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
