Abstract
The LASCAR project aims to conduct the first experimental study of the strong-field interaction of ultrashort laser pulses on a single Carbon nanotube (CNT) located at the apex of a Carbon cone, in order to produce ultrashort electron pulses and high harmonics on the nanoscale (Figure 1a). LASCAR is at the interface between « ultrafast physics » and « nano-technology », which both have experienced a spectacular fast growth in the last two decades, and combines both CEMES and LCAR expertise in those fields
The fundamental goal of LASCAR is to understand and control the different regimes of emission of the strong-field light-matter interaction between two simple systems with various controllable parameters: the Carbon nanotube on the one side is designed, fabricated and characterized by CEMES (Fig. 1b); the ultrashort laser pulse on the other side, for which the LCAR group has a long history in coherent control over various systems (atomic vapors, quantum dots, scattering media,…).
