Teams

The HXUV team studies the interaction of ultrashort and/or intense light pulses with matter in different phases – atoms, molecules and solids. Our team combines both experimental and theoretical activities relating to this theme. One of the most original subjects is the generation, control and metrology of high order harmonics of the laser field produced during such interactions. These XUV harmonics which are associated in the time domain with pulses of attosecond duration are then used to probe matter, in all its complexity. We develop time-resolved spectroscopies from attosecond to femtosecond with tunability from MIR to XUV with exotic polarization shaping/pulse characterization in duration, spatial mode as well as polarization state. Our experimental platforms are organized around the Aurora laser chain (1kHz-20mJ), the Eclipse laser chain (10Hz – 200 mJ) and the Blasbeat laser chain (166kHz to 2MHz) with several accessible endstations for photoelectron and mass spectroscopy, coincidences, and spectroscopy in the frequency and harmonic domains. All these approaches are applied to targets ranging from the gas phase to the condensed phase.
