Biography
Dr Allegre is a Lecturer in the Manufacturing Group at the Department of Mechanical & Aerospace Engineering. He specializes in advanced laser processes, with a special interest in high-power and ultrashort-pulse laser beam shaping to control laser interactions and tailor the produced materials microstructures and characteristics.
He also has a background in precision motion control, optics design and microscopy. Following the completion of a “diplôme d'Ingénieur” at Polytech’ Orleans in France in 2003, Dr Allegre worked as a Design and Software Engineer for research organisations such as NCRA in India, or industrial companies such as Marinovation in France and Thorlabs in Cambridge, UK. He joined Carl Zeiss SMT Ltd in 2007, where he worked as a Systems Engineer on the design and manufacture of electron microscopes. In 2009, he joined the University of Liverpool to complete a PhD in advanced control of laser beam wavefront and polarisation for micro-manufacturing. After his PhD in 2012, Dr Allegre managed an EU-funded project to promote the use of laser technologies to SMEs in the North-West.
Research interests
Dr Allegre's research interests focus on laser-material processing and modification, using advanced control techniques such as optical beam modulation. These can be used to tailor the processing of e.g. battery electrodes or photovoltaic cells, locally control microstructures in additively manufactured parts or produce nano-scale drilling for semiconductor devices.
Recent projects included:
- Shaping of laser-induced EM fields to drill materials at nanometric scales.
- Controlling laser interactions in diamond to produce radiation-hard detectors for medical and high-energy physics applications.
- Controlling materials characteristics and microstructures using high power optical beam modulation.
- Controlling selective materials response for tailored processing and modification of multilayered structures.
