Laser Driven Nuclear physics at ELINP

F. Negoita, M. Roth, P. G. Thirolf +53

High power lasers have proven being capable to produce high energy gamma rays, charged particles and neutrons to induce all kinds of nuclear reactions. At ELI, the studies with hig…

Atomic excitation during recollision-free ultrafast multi-electron tunnel ionization

W. A. Bryan, S. L. Stebbings, J. McKenna +12

Modern intense ultrafast pulsed lasers generate an electric field of sufficient strength to permit tunnel ionization of the valence electrons in atoms. This process is usually trea…

Isolated vibrational wavepackets in D2+: Defining superposition conditions and wavepacket distinguishability

W. A. Bryan, J. McKenna, E. M. L. English +9

Tunnel ionization of room-temperature D in an ultrashort (12 femtosecond) near infra-red (800 nm) pump laser pulse excites a vibrational wavepacket in the D2+ ions; a rotationa…

Mapping the Evolution of Optically-Generated Rotational Wavepackets in a Room Temperature Ensemble of D

W. A. Bryan, E. M. L. English, J. McKenna +7

A coherent superposition of rotational states in D has been excited by nonresonant ultrafast (12 femtosecond) intense (2 10 Wcm) 800 nm laser pulses lead…

On the recollision-free excitation of krypton during ultrafast multi-electron tunnel ionization

W A Bryan, S L Stebbings, J McKenna +7

The probability of multiple ionization of krypton by 50 femtosecond circularly polarized laser pulses, independent of the optical focal geometry, has been obtained for the first ti…

Geometry- and diffraction-independent ionization probabilities in intense laser fields: probing atomic ionization mechanisms with effective intensity matching

W. A. Bryan, S. L. Stebbings, E. M. L. English +11

We report a novel experimental technique for the comparison of ionization processes in ultrafast laser pulses irrespective of pulse ellipticity. Multiple ionization of xenon by 50…
