Journal ArticleDOI
Pulse slippage in high-gain, optically guided free-electron lasers
TL;DR: In this paper, the authors derived an expression for slippage in an optically guided free-electron laser (FEL) amplifier in the exponential regime and the optical beam is guided by the electron beam.
Proceedings ArticleDOI
Energy enhancement in a self‐modulated laser wakefield accelerator
TL;DR: In this article, a new configuration of the laser wakefield accelerator is proposed in which enhanced acceleration is achieved via resonant self-modulation of the light pulse, which requires laser power in excess of the critical power for relativistic guiding and a plasma wavelength short compared to the laser pulse length.
Proceedings ArticleDOI
Remote detection of radioactive materials using a near-terahertz gyrotron
V.L. Granatstein,Gregory S. Nusinovich,Phillip Sprangle,John C. Rodgers,Carlos Romero-Talamas,Ruifeng Pu,Dmytro Kashyn,Anatoly Shkvarunets +7 more
TL;DR: In this article, the authors studied new concepts for remote detection of concealed radioactive materials. But these concepts were not applied to the detection of hidden radioactive materials in the field of nuclear energy.
Proceedings ArticleDOI
Ultra‐intense laser interactions with beams and plasmas
Phillip Sprangle,Eric Esarey +1 more
TL;DR: The nonlinear interaction of ultra-intense laser pulses with electron beams and plasmas is rich in a wide variety of new phenomena, including laser excitation of large amplitude plasma waves (wakefields), relativistic optical guiding of laser pulses, optical guiding by preformed plasma channels, and cooling of electron beams by intense lasers as discussed by the authors.
Book ChapterDOI
Possibility of Recombination Gain Increase in CV Ions at 4.0 nm Via Coherence
Y. Luo,A. Morozov,Daniel Gordon,Phillip Sprangle,Anatoly A. Svidzinsky,Anatoly A. Svidzinsky,Hui Xia,Hui Xia,Marian O. Scully,Marian O. Scully,Szymon Suckewer +10 more
TL;DR: In this article, the authors discussed the possibility of applying a recently developed theory of Lasing Without Inversion (LWI) in XUV and X-ray regions to largely increase the gain for such transitions.
