Report

Transition between mechanisms of laser-induced field-free molecular orientation

Autor: Znakovskaya, Irina, Spanner, Michael, De, Sankar, Li, Hui, Ray, Dipanwita, Corkum, Paul, Litvinyuk, Igor V., Cocke, C. Lewis, Kling, Matthias F.

The transition between two distinct mechanisms for the laser-induced field-free orientation of CO molecules is observed via measurements of orientation revival times and subsequent comparison to theoretical calculations. In the first mechanism, which

Ejection of quasi-free electron pairs from the helium atom ground state by single photon absorption

Autor: Schöffler, M. S., Stuck, C., Waitz, M., Trinter, F., Jahnke, T., Lenz, U., Jones, M., Belkacem, A., Landers, A., Pindzola, M. S., Cocke, C. L., Colgan, J., Kheifets, A., Bray, I., Schmidt-Böcking, H., Dörner, R., Weber, Th.

We investigate single photon double ionization (PDI) of helium at photon energies of 440 and 800 eV. We observe doubly charged ions with close to zero momentum corresponding to electrons emitted back-to-back with equal energy. These slow ions are the

Report

Field-free orientation of CO molecules by femtosecond two-color laser fields

Autor: De, S., Znakovskaya, I., Ray, D., Anis, F., Johnson, Nora G., Bocharova, I. A., Magrakvelidze, M., Esry, B. D., Cocke, C. L., Litvinyuk, I. V., Kling, M. F.

Publikováno v: Phys.Rev.Lett. 103, 153002 (2009)

We report the first experimental observation of non-adiabatic field-free orientation of a heteronuclear diatomic molecule (CO) induced by an intense two-color (800 and 400 nm) femtosecond laser field. We monitor orientation by measuring fragment ion
