The CORIA laboratory opens a PhD position in the field of ultrafast optics.
Project description
Laser frequency combs are coherent light sources whose spectrum consists of a series of discrete and equally spaced frequency lines. They provide an extremely high-precision tool for numerous metrology and spectroscopy applications, and their importance was recognized worldwide with the 2005 Nobel Prize awarded to T.W. H nsch and J. Hall [1]. Their development towards the visible and near-infrared region has permitted myriads of new applications, and extending these techniques towards the mid-infrared region could lead to several promising applications, such as high-precision spectroscopy in the so-called fingerprint region [2]. This PhD thesis is thus organized along two main axes, to be carried out within the Optics & Lasers Department of the CORIA. The fist axis will consist in studying and perfecting innovative MIR ultrafast laser sources that are currently under development in the lab [3,4], in order to tailor them to several spectroscopy applications. The second part of this work will be to apply the previously built laser frequency combs to several high-precision and ultrafast MIR-spectroscopy applications through the dual-comb spectroscopy (DCS) technique. The DCS technique will then be used to study several phenomena, such as real-time molecular spectroscopy in reactive flows or catalysis. High-impact outcomes are expected for both axes of the PhD thesis and through several scientific collaborations.
Job profile
The applicant should hold a MSc diploma in the fields of photonics or applied physics, with theoretical and experimental skills on laser physics, spectroscopy and/or nonlinear optics. The candidate should also have the capacity to work within an international team and to collaborate with other groups in the lab.
