“…While for resolving the atomic motion in molecules in time, for example, by creating and taking snapshots of a vibronic wavepacket, laser pulses with duration of several femtoseconds (10 −15 s) are sufficient, accomplishing a similar feat for the electronic motion in atoms, molecules, or condensed matter requires sub-femtosecond, that is attosecond (as), time resolution (1 as = 10 −18 s). Advances during the last decade in the development of phasecontrolled few-cycle infrared (IR) laser pulses (cycle period IR ≃ 2.7 fs at = 800 nm) and ∼ 100 attosecond XUV pulses, temporally well correlated with each other through the underlying high-harmonic generation (HHG) process Hentschel et al, 2001;Paul et al, 2001) have opened up the possibility to observe and to control electronic dynamics in matter in real time and has developed into a new field dubbed attosecond physics (see e.g., Agostini and Dimauro, 2004;Reider, 2004;Scrinzi et al, 2006;Corkum and Krausz, 2007;Bucksbaum, 2007;Kling and Vrakking, 2008;Krausz and Ivanov, 2009;Chang, 2011;Gallmann et al, 2012;Plaja et al, 2013;Schultz and Vrakking, 2013;Kim et al, 2014;Lepine et al, 2014;Krausz and Stockman, 2014;Peng et al, 2015, for reviews of the subject). Previously, time-resolved electronic dynamics was accessible only for high-lying excited states.…”

“…The interaction of strong laser fields with atoms or molecules can lead to high-order harmonic generation(HHG), which can be applied as table-top coherent light sources in a wide frequency range [1][2][3][4]. Recently, much attention has been paid to the below or near-threshold harmonics because of its potential applications as coherent vacuum-ultraviolet light sources in different circumstances [5][6][7][8][9].…”

“…Импульсы с длительностью порядка периода колебаний световой волны, безусловно, найдут многочисленные приме-нения в фундаментальных и прикладных исследованиях [1][2][3][4]. Эффективная генерация ПКИ позволила бы применять их для сверхбыстрого управления процессами в веществе, создавать новые типы ускорите-лей электронов и ионов.…”

“…В работах [9,10] была рассмотрена возможность генерации ПКИ непосредственно в лазере при условии когерентного взаимо-действия света с веществом, в режиме так называемой когерентной синхронизации мод. Когерентное взаимодействие света с веществом возникает, когда длительность импульса света τ p меньше времени релаксации поляризации среды 2 T , 2 τ p T  [15]. Наличие «фазовой памяти» 2 T меняет картину распро-странения света в резонансной среде.…”
