Objectives of the Optics & Lasers department:
- Fundamental research in Optics, especially towards the development of laser sources and light-matter interactions, with the general purpose of developing optical diagnostics.
- Transfer of our concepts to other departments of the laboratory for applications to the metrology of reactive and non-reactive flows, but also to other national and international laboratories.
- Collaboration with several industries.
- Strong commitment in training (teaching, head of Master, head of engineer school, doctoral school…)
In particular, the Optics & Lasers department covers the following research fields:
- Theoretical optics (historical field)
- Ultrafast laser sources (bulk and fiber sources, near and mid- R, parametric oscillators)
- Digital holography : theory and applications (speed measurements, particles tracking)
- Interferometric imaging of particules (index measurement, droplets evaporation rate…)
- Soot nanoparticles diagnotics (light-aggregate interaction models, metrology, health impact…)
- Rainbow refractometry (icing, liquid combustion, CO2 capture by droplets…)
- Complex vectorial ray tracing models (liquid system imaging and interference calculation)
- Real-time metrology and ultrafast dynamics (nonlinear dynamics, high-speed imaging)
