Nonlinear Processes of Atoms in Intense EUV Free-Electron Laser Fields

Fushitani Mizuho, Hikosaka Yasumasa, Hishikawa Akiyoshi

Butsuri Vol. 68 ( 12 ) page： 794 - 801 2013

Language：Japanese Publisher：The Physical Society of Japan

The advances in free electron laser (FEL) technology allow us to generate intense laser fields in extreme ultraviolet (EUV) and X-ray. Recent studies show that responses of materials to such high-frequency intense laser fields are inherently different from those observed in visible and infrared. In this reveiw, we discuss current progresses in intense laser field physics in EUV and X-ray, especially by focussing on non-linear responses of isolated atoms.

Single-shot photoelectron spectroscopy of multiphoton ionization of atoms irradiated with EUV-FEL pulses

HIKOSAKA Yasumasa, FUSHITANI Mizuho, HISHIKAWA Akiyoshi

しょうとつ(Web) Vol. 9 ( 1 ) page： 5 - 10 2012

Language：Japanese

Multiphoton ionization is a typical nonlinear response of atoms in intense EUV laser fields. Single-shot photoelectron spectroscopy utilizing with a magnetic-bottle-type electron spectroscopic technique is a useful means to study the details of multiphoton multiple ionization processes. We present that the method enables us to monitor the fluctuation of SASE-FEL spectra and to derive photon energy dependence of the multiphoton multiple ionization processes precisely.

Real-Time Reaction Probing by Laser Coulomb Explosion Imaging

The Review of Laser Engineering Vol. 40 ( 10 ) page： 745 - 745 2012

Language：Japanese Publisher：The Laser Society of Japan

Molecules exposed to few-cycle intense laser fields (> 1014 W/cm2) undergo a rapid bond breakingprocess called Coulomb explosion. Since the momenta of the resultant fragment ions reflect thegeometrical structure of the target molecule, Coulomb explosion provides a direct access to theinstantaneous structure of molecules during chemical reaction. Combined with the pump-probe schemein ultrafast spectroscopy, Coulomb explosion imaging serves as a unique means to probe ultrafastmolecular reaction processes in real time. Here we review this novel approach in ultrafast spectroscopy,with the applications to ultrafast isomerization of deuterated acetylene dication (C2D22+).
