Department description

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, tracking of shock waves)
