For more Science Videos: https://lt.org/ * Lasers typically produce a Gaussian beam where intensity is greatest in the center and tails off at the edges. In this video, ULRIKE FUCHS explains how a laser beam profile can be transformed into something more effective for material processing. * Drawing on insights from phase shifting microscopy, Fuchs shows how a phase plate can be used to change the phase distribution of an incoming Gaussian beam before it is focused. * Along with making existing processes faster, more efficient and more precise, Fuchs’s work reveals potential for exciting new applications for laser technology going forward. * For further Information, visit: https://www.asphericon.com/news/detail/vp-der-asphericon-zum-osa-fellow-ernannt This LT Publication is divided into the following chapters: 0:00 Question 1:14 Method 3:10 Findings 5:32 Relevance 6:53 Outlook

For more Science Videos: https://lt.org/ * It has been heretofore understood that patterns of cloudiness are controlled by large scale weather systems. In this video, BJORN STEVENS challenges this orthodoxy, arguing that small and intermediate scales of motion play a key role in determining the Eart

FUCHS analyzes the degradation of such algae, exploring which organisms are involved and what they actually do. * Employing
