Missions

We are seeking a talented and motivated researcher with expertise in picosecond acoustics and laser ultrasonics. The experimental researcher will conduct fully optical picosecond acoustic measurements on multilayer opaque materials, combined with dynamic loading experiments and high-intensity laser injection.

Activities

The research project involves implementing and operating an optical experimental setup based on a femtosecond laser for time-resolved measurements of acoustic phonons in opaque and/or semi-transparent materials.
The femtosecond setup must be coupled and synchronized with a sub-nanosecond system capable of applying intense dynamic stresses simultaneously with picosecond acoustic phonons and/or with optical injection of electron flux.
The researcher will be responsible for:
-preparing and mounting samples;
-conducting picosecond acoustics experiments;
-performing non-destructive shock-wave experiments;
-acquiring, analyzing, and interpreting experimental data.
The independent researcher is expected to propose new ideas, publish results in high-impact journals, and present findings at international conferences.

Skills

PhD in Applied Physics, Physics, or Optics.
Strong mastery of pump-probe techniques and picosecond acoustics.
Experience with programming and data acquisition (Matlab, LabVIEW at minimum).
Fluency in written and spoken English and French.
Interest in multidisciplinary research.

Work Context

The researcher will work autonomously and carry out laser ultrasonics experiments within a multidisciplinary project, in collaboration with members of the CNRS IETR laboratory.

Constraints and risks

Potential exposure to high-power laser sources.
