Journal ArticleDOI
Photon lifetime in a cavity containing a slow-light medium.
T. Lauprêtre,C. Proux,Rupamanjari Ghosh,Sylvain Schwartz,Fabienne Goldfarb,Fabien Bretenaker +5 more
TL;DR: In this paper, the authors investigated the lifetime of the photons in a cavity containing a medium exhibiting strong positive dispersion, provided by a metastable helium gas at room temperature in the electromagnetically induced transparency regime.
Journal ArticleDOI
Photon lifetime in a cavity containing a slow-light medium
T. Lauprêtre,C. Proux,Rupamanjari Ghosh,Sylvain Schwartz,Fabienne Goldfarb,Fabien Bretenaker +5 more
TL;DR: The results definitely prove that the lifetime of the cavity photons is governed by the group velocity of light in the cavity and not its phase velocity.
Journal ArticleDOI
Gain dynamics in a soft-X-ray laser amplifier perturbed by a strong injected X-ray field
Yong Wang,Shoujun Wang,Eduardo Oliva,Lianhe Li,Lianhe Li,Mark Berrill,Liang Yin,Jaroslav Nejdl,B. M. Luther,C. Proux,T. T. T. Le,James Dunn,David Ros,Ph. Zeitoun,Jorge J. Rocca +14 more
TL;DR: In this paper, the first X-ray pump-X-ray probe measurement of the nonlinear response of a plasma amplifier perturbed by a strong soft-Xray ultra-short pulse is reported.
Proceedings ArticleDOI
Decay time in a cavity in slow or fast light regime
T. Lauprêtre,C. Proux,Rupamanjari Ghosh,Sylvain Schwartz,Fabienne Goldfarb,Fabien Bretenaker +5 more
TL;DR: In this paper, the authors investigated the decay time of a cavity in the presence of positive or negative dispersion and found that the phase velocity rules the decay rate of the cavity, while other studies assume that this decay time is connected to the group velocity.
Book ChapterDOI
Gain Dynamics in Injection-Seeded Soft X-Ray Laser Plasma Amplifiers
Shoujun Wang,Yong Wang,Eduardo Oliva,Lianhe Li,Mark Berrill,Liang Yin,Jaroslav Nejdl,B. M. Luther,C. Proux,T. T. T. Le,James Dunn,D. Ros,Ph. Zeitoun,Jorge J. Rocca +13 more
TL;DR: In this article, Wang et al. measured the gain dynamics in an injection-seeded soft x-ray plasma amplifier and showed that the regeneration of the population inversion that follows the gain depletion caused by the amplification of the first seed pulse takes place in about 1.75 ps.
