Appropriate beam shaping enables those improvements by decreasing the process defects and by allowing welding of new types of materials and of thinner parts. We describe here the design and the process test results of a fully reflective beam shaper laser head compatible with high-power lasers demands integrated on a robot. The high efficiency cooling permitted by a reflective design reduces focus shift. A mm-wide annular shape onto the processed part enables melt pool size control.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\" style=\"margin-top:0;margin-bottom:0\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.researchgate.net\/publication\/339804230_Fully_reflective_annular_laser_beam_shaping_for_103m_ultra-high_throughput_laser_beam_welding_Conference_Presentation\" target=\"_blank\" rel=\"noreferrer noopener\">More information<\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Photonics West 2020<\/p>\n","protected":false},"author":2,"parent":0,"template":"","categorie-publication":[101,110],"class_list":["post-5664","publication","type-publication","status-publish","hentry","categorie-publication-procedes-laser-industriels","categorie-publication-soudage-laser"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
