Experimental Demonstration of Laser Temporal Coherence Effects on Multiphoton Ionization Processes
A single-transverse-mode Q-switched Nd-glass laser, which can operate over a variable number of longitudinal modes, has been used to investigate the influence of the temporal nature of the laser pulse on the multiphoton ionization probability of xenon atoms. For a seven-mode laser pulse, the number of ions formed is increased by several orders of magnitude over that produced by a single-longitu...
متن کاملElectron Correlation Effects in Nonresonant Multiphoton Ionization Processes
The role of electron correlations in nonresonant multiphoton processes of atoms is presented. The evidence for the validity of a lowest order perturbation theory (LOPT) approach for the laser field in the case of nonresonant processes is sketched. The growing consensus for a LOPT interpretation of even the multiply-charged ion spectra obtained with high intensity lasers is reviewed. Finally, a ...
متن کاملLaser temporal and spatial effects on ionization suppression
Ionization suppression can be defined as the decrease of photoinduced atomic ionization rates with an increased applied field intensity. The temporal and spatial intensity distribution of a focused laser pulse introduces difficulty in observing ionization suppression. An analysis of the effect of a temporally Gaussian laser pulse on ionization suppression from Rydberg levels is given. It is fou...
متن کاملEffects of coherent coupling of autoionizing states on multiphoton ionization.
coherent coupling of autoionizing states on multiphoton ionization" (1996). C. We present the experimental and theoretical investigation of the effects of the strong electromagnetic coupling of two autoionizing states (AIS's) on the photoionization properties of an atomic system. These effects are observed by probing the ladder system from the ground state of the atom through a weak two-photon ...
متن کاملMultiphoton ionization of H2+ in xuv laser pulses
We consider the ionization of the hydrogen molecular ion after one-, two-, and three-photon absorption over a large range of photon energies between 9 and 40 eV in the fixed-nuclei approximation. The temporal development of the system is obtained in a fully ab initio time-dependent grid-based approach in prolate spheroidal coordinates. The alignment dependence of the one-photon ionization ampli...
