General information

Reference : UMR5588-DIDMON-002
Date of publication : Monday, May 18, 2020
Type of Contract : FTC Scientist
Contract Period : 12 months
Expected date of employment : 1 September 2020
Proportion of work : Full time
Remuneration : from 2648.79 to 3054.06 euros gross salary
Desired level of education : PhD
Experience required : 1 to 4 years


In the frame of COMPLEAT project funded by ANR, the post-doc will take in charge the recordings of infrared absorption spectra of different gas mixtures using ultra-sensitive laser techniques, namely Cavity Ring Down spectroscopy (CRDS) and Optical-feedback Cavity Enhanced absorption spectroscopy (OF-CEAS). He/she will take part of the data treatment and analysis. He/she will also be involved in the duplication of a thermalized high finesse absorption cell and its installation in the different CRDS spectrometers.


- Duplication and installation of a thermalized CRDS cell (Main task)
- recordings of spectra for H2/CO2 mixtures for different temperatures and spectral regions of the infrared by CRDS (Main task)
- recordings of spectra for H2O/CO2 mixtures for different temperatures and spectral regions of the infrared by CRDS and OF-CEAS (Main task)
- Data treatment and analysis (Main task)


The person recruited has to be familiar with ultra-sensitive absorption techniques and particularly with CRDS to be directly operational for measurements. He/she has to show a great autonomy during the measurements and the realization of the thermalized cell.
Meticulousness and organization are also two main qualities we are looking for.

Work Context

The Laboratoire Interdisciplinaire de Physique (LIPhy) is a research unit (UMR 5588) depending on CNRS and University of Grenoble Alpes. The LIPhy is located at the Saint Martin d'Hères' campus on the east side of Grenoble. The laboratory has approximately 150 members including 66 researchers and professors, 32 engineers, technicians and administrative staff and 39 PhD students. The lab is structured in seven teams of various sizes, with a broad scope of interests. These different teams address scientific questions mainly in the fields of Optics, Complex matter, and Living matter. Our group, named LAME (Lasers Molécules et Environnement), is particularly involved in the development of high-sensitivity/high precision laser-based absorption spectroscopy techniques for atmospheric and planetology applications as well as for detection of trace gases. In particular, since about 20 years we exploit high finesse optical cavities to increase the interaction of light with a (gaseous) sample to achieve effective absorption path lengths up to hundreds of km.
