Making ultrafast lasers faster
- Published on 12 June 2019
The consortium consists of the research institute Fraunhofer ILT and the RWTH Aachen University from Germany as well as Amplitude Systèmes, LASEA France, AA Opto-Electronic from France and LASEA from Belgium as industrial research and development partners. The European Commission is supporting the project, named “MultiFlex”, within the framework of the program ICT-04-2018 for three years with an amount of € 4.7 million.
The partners intend to deliver a prototype with all the necessary control technology ready for the shop floor. It will start with a 1 kW laser machine that can deliver up to 1 mJ pulse energy either at the regular 1 MHz repetition rate or in a burst mode with less than 20 ns pulse separation. It has already been estimated that the prototype will improve the productivity by about 100 fold compared to current standard ultrafast laser processing systems.
