Theory of a filament initiated nitrogen laser
Daniil Kartashov,Daniil Kartashov,Skirmantas Alisauskas,Audrius Pugžlys,Mikhail N. Shneider,Andrius Baltuška +5 more
TL;DR: In this paper, a single-pass discharge-type standoff nitrogen laser initiated by a femtosecond filament in nitrogen gas is modeled and the model is based on the numerical solution of the kinetic equation for the electron energy distribution function self-consistently with balance equations for nitrogen species and laser equations.
Journal ArticleDOI
Carrier-envelope-phase dependence of asymmetric CD bond breaking in C2D2 in an intense few-cycle laser field
Shun Miura,Toshiaki Ando,Kazuki Ootaka,Atsushi Iwasaki,Huailiang Xu,Tomoya Okino,Kaoru Yamanouchi,Dominik Hoff,T. Rathje,Gerhard G. Paulus,Markus Kitzler,Andrius Baltuška,Giuseppe Sansone,Mauro Nisoli +13 more
TL;DR: In this article, the carrier envelope phase (CEP) dependence in the CD bond breaking of C2D2 induced by an intense few-cycle laser pulse was investigated, and the ejection direction of D+ ions generated from the Coulomb explosion was attributed to the laser-assisted CD bond weakening in the fewcycle laser field.
Journal ArticleDOI
Extreme Raman red shift: ultrafast multimode nonlinear space-time dynamics, pulse compression, and broadly tunable frequency conversion
Paolo Carpeggiani,G. Coccia,Guangyu Fan,E. Kaksis,Audrius Pugžlys,Andrius Baltuška,Riccardo Piccoli,Young-Gyun Jeong,Andrea Rovere,Roberto Morandotti,Luca Razzari,Bruno E. Schmidt,A. A. Voronin,Aleksei M. Zheltikov +13 more
TL;DR: In this paper, a continuous red shift provided by stimulated Raman scattering (SRS) over a long propagation distance in nitrogen-filled hollow-core fibers (HCF) was used to achieve a continuous tunability of the laser wavelength from 1030 nm up to 1730 nm with a conversion efficiency higher than 70%.
Journal ArticleDOI
Wave Packet Dynamics in Ultrafast Spectroscopy of the Hydrated Electron
TL;DR: In this paper, the frequency-resolved pump-probe experiments using pulses of 13 fs centered at 780 nm were examined for hydrated-electron dynamics, showing that the pump pulse produces an ultrafast red-shift of the electronic transition by approximately 6500 cm-1.
Journal ArticleDOI
Self-compression of high-peak-power mid-infrared pulses in anomalously dispersive air
Aleksandr V. Mitrofanov,A. A. Voronin,M. V. Rozhko,Dmitry A. Sidorov-Biryukov,Andrei B. Fedotov,Audrius Pugžlys,Valentina Shumakova,Skirmantas Alisauskas,Andrius Baltuška,A. M. Zheltikov +9 more
TL;DR: In this paper, the authors identify and experimentally demonstrate a physical scenario whereby high-peak-power mid-infrared (mid-IR) pulses can be compressed as a part of their free-beam spatiotemporal evolution within the regions of anomalous dispersion in air to yield few-cycle subterawatt field waveforms.
