Application Deadline: 15/02/2022 23:59 - Europe/Brussels

Location: France › BESANCON

Type Of Contract: Temporary

Job Status: Full-time

Hours Per Week: 35

Offer Starting Date: 02/05/2022

Research will be carried out within the CNRS FEMTO-ST Institute in a newly commissioned scientific building providing access to a wide range of basic science and technological facilities including a suite of dedicated photonics laboratories, 1300 m2 of clean rooms, and parallel computing center. Besancon is in the East of France, 2 hours 15 minutes from Paris by train and near the foothills of the Jura mountains, close to excellent hiking and mountain bike trails, ski stations and rock-climbing formations. It is consistently rated as having one of the highest qualities of life in France and has a vibrant university atmosphere.

The FEMTO-ST Institute seeks highly motivated PhD student to work within a project combining experimental and numerical research which aims at pushing the frontiers of laser material processing by controlling the laser-plasma interaction.

Ultra-intense femtosecond laser pulses promise to become a fast, universal, predictable and green tool for material processing at micro and nanometric scale. The recent tremendous increase in commercially available femtosecond laser energy at high repetition rate opens a wealth of novel perspectives for mass production. But even at high energy, laser processing remains limited to high-speed scanning point by point removal of ultra-thin nanometric layers from the material surface. This is because the uncontrolled laser-generated free-electron plasma shields against light and prevents reaching extreme internal temperatures at very precise nanometric scale. Our project aims at breaking this barrier and developing a radically different concept of laser material modification regime based on free-electron plasma control.

The main objective of the PhD thesis is to consolidate an experimental setup built to image nano-plasmas generated by ultrashort laser pulses and to study the laser-matter interaction in this regime.
