Gilles Cheriaux has been named senior scientist at National Energetics to further the company's development of components and systems for ultraintense lasers. Cheriaux will work with the company's Northeast team on the L4 10-PW laser for the Extreme Light Infrastructure Beamlines project in the Czech Republic, a laser facility that aims to host the most intense laser system in the world. Recognized as a premier laser scientist in the development of ultraintense laser systems, Cheriaux has spent more than 15 years at École Polytechnique and the French National Centre for Scientific Research. He was instrumental in the development of the large amplifier elements of the Apollon-10P system, as well as integration of adaptive optics and advanced pulse cleaning methodologies using cross-polarized wave generation. Cheriaux received his doctorate from École Polytechnique's Applied Optics Lab and completed his postdoctoral studies at the Center for Ultrafast Science at the University of Michigan. National Energetics designs and constructs high-energy and ultraintense lasers and laser systems based on chirped pulse amplification.
