Amplified femtosecond laser systems allow, due to their high power, to explore new physical phenomena such as filamentation laser, where the laser beam propagates over...

This thesis is divided in two parts : i) the laser channeling in hundreds of microns long under-dense plasmas (0.1nc<n<nc, nc being the critical density) of a...

We have developed a real-time optical technique that discriminates bioaerosols among urban background aerosols, especially soot emitted by diesel engines. This...
