Plasma Physics and Secondary Sources

Using the ASUR platform, we study and operate pulsed hard X-ray sources induced by high peak-power high-average power laser sources with the perspective to develop imagery and X-ray diffraction diagnostics for material and life science [Sci. Rep. 10, 6766 (2020)] [Opt. Lett. 43, 3574 (2018)].

Emergent Technologies

We have developed a unique workstation to understand and develop laser inscription inside silicon bulk with IR short-pulse laser for exploring future 3D inscription applications in micro-electromechanics and silicon photonics. (user access provided) [Phys. Rev. Applied 12, 024009 (2019)] [Opt. Express 28, 26623 (2020)].

Laser Technology and Optics

We developed a well-mastered well-controlled metrology of laser damage addressing the technically-complex ultrashort regime with the perspective to benchmark new innovative robust materials and optical components for high peak-power laser installations (user access provided, collaboration and contracts with industry [Adv.

LP3 Laboratory is a Joint Research Unit of Aix-Marseille University (AMU) and CNRS. LP3 conducts original research on the physics of pulsed laser-matter interactions and the development of new laser-based processes. To develop its research, the laboratory relies on a staff of about thirty people (19 permanent staff) with diversified skills and expertise (optics and lasers, physics and material sciences, physical-chemist/biologist), and operates a rich and unique set of laser sources and advanced in-situ and ex-situ diagnostics.

Even if rather modest in size, the LP3 laboratory is a major national and international player in many fields of pulsed laser-matter interaction, including ablation and plasma diagnostics, LIBS spectroscopy, laser plasma X-ray source generation and in the development of innovative processes and laser-based procedures for the functionalization and transformation of matter. Recent achievements encompass 3D laser writing in silicon, 3D (sub)-micrometric additive printing, laser-synthesis of nanoparticles and development of theranostics processes, and (sub)micro-structuration of dielectrics materials. Moreover, the laboratory operates two high-tech laser platforms (ASUR: Applications of Ultra-Fast Sources and LaMP: Lasers for Micro-Processes) attracting local, national and international socio-economic actors from various horizons. This allows us developing a large volume of contracts which makes the lab a top partner for industry.

Equipment offered to external users

LP3 operates a large set of pulsed laser sources, from ns to fs, and from UV to near IR. It is also equipped for in-situ (high speed imaging, pump-probe, spectroscopy, etc.) and ex-situ (SEM, AFM, confocal and optical microscopes, ellipsometer, SNOM-RAMAN …) characterization of laser matter interaction, plasmas and samples. These facilities allow LP3 researchers to perform complete studies from well-mastered laser source to matter processing, sensing or imaging technologies, and laser-fabrication innovative demonstrators. Among the numerous (> 15) laser sources of LP3, it is worth noting that one is unique in the world: a 100 Hz – 10 TW- 25fs Ti:Sa laser (ASUR platform).
