Circularly polarized laser field-induced rescattering plateaus in electron-atom scattering
نویسندگان
چکیده
We analyze the laser ellipticity dependence of n-photon differential cross sections (dσn/dΩ) for electron-atom scattering in an intense elliptically polarized laser field. We show that there exist two plateau-like structures in the dependence of dσn/dΩ on n for any ellipticity, including for the case of circular polarization. We present numerical predictions for e-H scattering in a CO2-laser field and an analytical description of the plateau features in terms of the rescattering scenario.

Controlling Nonsequential Double Ionization in Two-Color Circularly Polarized Femtosecond Laser Fields.
Atoms undergoing strong-field ionization in two-color circularly polarized femtosecond laser fields exhibit unique two-dimensional photoelectron trajectories and can emit bright circularly polarized extreme ultraviolet and soft-x-ray beams. In this Letter, we present the first experimental observation of nonsequential double ionization in these tailored laser fields. Moreover, we can enhance or...
متن کاملun 2 00 3 Electron rescattering and the fragmentation dynamics of molecules in strong optical fields
We have probed the fragmentation dynamics in a bent triatomic molecule, water , a non-planar molecule, methanol, and a planar ring-structured molecule, benzene, using 100 fs duration pulses of linearly and circularly polarized, in-frared, intensity-selected laser light. At laser intensities larger than 10 15 W cm −2 , the yield of singly and multiply charged atomic fragments from these molecule...
متن کاملElastic scattering and impact ionization by returning electrons induced in a strong laser field
We study elastic scattering and impact ionization by returning electrons induced in a strong laser field based on the recently developed quantitative rescattering theory. The high-energy angle-resolved photoelectron spectra of molecules in strong fields are attributed to elastic scattering of the returning electrons with the parent ion. We demonstrate that the high-energy photoelectron spectra ...
متن کاملEvidence for rescattering in intense, femtosecond laser interactions with a negative ion.
It is now well established that energetic electron emission, nonsequential ionization, and high harmonic generation, produced during the interaction of intense, femtosecond laser pulses with atoms (and atomic positive ions), can be explained by invoking rescattering of the active electron in the laser field, the so-called rescattering mechanism. In contrast for negative ions, the role of rescat...
متن کاملTomographic Reconstructions of Photoelectron Distributions from Strong-Field Ionization in Two-Color Circularly Polarized Laser Fields
In this experiment, we propagate superposed 800 nm and 400 nm circularly polarized driving laser fields and interact the combined field with argon gas—in doing so, we demonstrate strong field ionization from this interaction. We then use velocity map imaging and tomographic reconstruction techniques to look at the resulting photoelectron angular distributions. From this, we discover that if the...
