Ultrafast dynamics in CO2 studied by XUV-pump - NIR-probe experiments

Abstract

We present the results of an XUV-pump - NIR-probe experiment studying ultrafast dynamics of photo-ionized CO2. The multi-harmonics XUV pulse, which contains the 11th to 39th harmonics of a 790 nm nearinfrared (NIR) laser, is used to excite molecular wave packets in CO2+, which are then probed by a near-infrared pulse that induces dissociation. The yields and angle-resolved kinetic energy distributions of all charged fragments are measured as a function of the XUV-NIR delay using a velocity map imaging setup.
