Lasers et Biophotonique

Laser and Biophotonic is divided into two groups:

ELSA

We are a group of highly motivated scientists working on the development of new solid-state lasers and their applications. Our work begins with the study of new diode-pumped solid-state gain media: crystals, fibres and semiconductor structures, in order to cover a wide range of wavelength and time domain (cw to the femtosecond regime), by studying novel architectures including non linear optical functions for beam quality improvment and for reaching the visible-blue wavelength range. Our activity triggers numerous applications in biophotonics (fluorescence lifetime microscopy, high resolution imaging, eye surgery), metrology (optical frequency standards) and solid-state physics (harmonics generation, micromachining). The ELSA team is involved in the ILE (Institut de la Lumière Extrême) project and is in charge of the development of the front-end of the 10 PW Appolon laser facility.

MACSYBIO

Our research activities are centered on plasmonics and its application in the field of optical biochips. Real-time monitoring of the biochip surface with sub-nanometer sensitivity is made possible using the Surface plasmon resonance effect in a metallic layer. Nanostructures on the surface can further increase the sensitivity and the information density of the biochip with applications in biomolecular analysis.
