Improving the energy efficiency of energy production or propulsion systems requires a better understanding of the multiple processes involved, a key point for relevant innovations. This objective, which is based on the ability to characterize the progress of reactions and the production of pollutants in situ, is based on the availability of efficient laser diagnostics. This project aims to create an international level center of expertise in the development and exploitation of ultra-fast laser sources in the energy field. It draws on the unique expertise of three Norman laboratories: the Research Center on Ions, Materials and Photonics (CIMAP), the Interdisciplinary Research Complex in Aerothermochemistry (CORIA) and the Catalysis and Spectrochemistry Laboratory (LCS), which have expertise ranging from the development of new materials and the development of ultrafast lasers to the implementation of innovative optical diagnostics in combustion systems and the study of depollution processes by catalysis. The CORIA laboratory is the holder of the PERCEVAL industrial chair (ANR/SAFRAN Tech) which aims to develop and analyze the aeronautical technologies of tomorrow and the use of ultra-rapid laser diagnostics for the study of high-pressure combustion. Ultrafast sources operating at high rates beyond kHz while retaining significant energies open up perspectives for the temporal monitoring of the evolution of physical quantities measured in complex environments, which represents a major advance compared to the same diagnostics operating in the nanosecond regime at a rate of around ten Hz. Another very promising application of these high rate sources concerns the dynamic study of reaction mechanisms in depollution processes by catalysis. Current developments in these areas are based on commercial laser systems which are based on massive crystals mainly of titanium-doped sapphire. However, these systems are limited in throughput due to thermal problems in the crystals. Emerging technologies, based on optical fibers or advanced crystalline architectures pumped by diodes, are paving the way for the production of ultrashort, high-energy light pulses at rates of several tens of KHz. In this context, the CORIA laser team has acquired extensive experience in the development of ultra-fast laser sources based on optical fibers, as evidenced by its numerous innovations in the field (three patents, one of which is the subject of an industrial exploitation license).
