Wakefield generation in one-dimensional LWFA

Vanchinkhuu, J
Bilikmen, S
The generation of wakefields in near-critical density plasma by a short laser pulse is considered. The equations describing the plasma response to the acting laser pulse and the Hamiltonian of an electron in the wakefield are derived by using the Hamilton-Jacobi equation for the cases of nu (g) similar or equal to nu (p) similar or equal to w = c w < c (e is the speed of light). The equations are solved analytically in two cases for a square-shaped laser pulse. The plasma potential inside the laser pulse and the wakefield potential excited by the laser pulse are obtained. The optimal length of the driving laser pulse and the wavelength of the wake are expressed by the group velocity.


Wakefield by a short laser pulse
Vanchinkhuu, J; Bilikmen, S (2000-09-07)
The equation describing the plasma response to the acting laser pulse is derived by using the Hamilton-Jacobi equation for the case nu (g) approximate to nu (ph) approximate to w less than or equal to c. The equation is solved numerically for one-dimensional Gaussian pulse and analytically for a square-shaped laser pulse. It is shown that the amplitude and the wavelength of the wake wave depend strongly on the amplitude and the length of the laser pulse.
Limits on laser wakefield accelerators
Yedierler, Burak (1999-04-01)
The longitudinal and radial wakefields produced by a single laser pulse in a plasma are calculated. The limits on the laser wakefield acceleration because of diffraction, optical guiding, and energy loss due to radiation are examined. In particular for a bi-Gaussian laser beam, the energy gain about 4.6 GeV/cm s is estimated. A general constraint on the plasma density is presented. All the limits are compared and a localized density channel of width 4.6 x 10(-5) cm is proposed. (C) 1999 American Institute o...
HESS observations of PKS 2155-304
Aharonian, F; et. al. (2005-02-01)
The high-frequency peaked BL Lac PKS 2155-304 at redshift z=0.117 has been detected with high significance (similar to45sigma) at energies greater than 160 GeV, using the H.E.S.S. stereoscopic array of imaging air-Cherenkov telescopes in Namibia. A strong signal is found in each of the data sets corresponding to the dark periods of July and October, 2002, and June-September, 2003. The observed flux of VHE gamma rays shows variability on time scales of months, days, and hours. The monthly-averaged integral f...
Curvature aided long range propagation of short laser pulses in the atmosphere
Yedierler, Burak (AIP Publishing, 2013-3)
The pre-filamentation regime of propagation of a short and intense laser pulse in the atmosphere is considered. Spatiotemporal self-focusing dynamics of the laser beam are investigated by calculating the coupled differential equations for spot size, pulse length, phase, curvature, and chirp functions of a Gaussian laser pulse via a variational technique. The effect of initial curvature parameter on the propagation of the laser pulse is taken into consideration. A method relying on the adjustment of the init...
Analysis of preformed plasma condition of Ni-like Mo X-ray laser media
İnce, Sevi; Bilikmen, Kadri Sinan; Department of Physics (2006)
The aim of this work is to produce X-ray laser source from a plasma produced by focusing a pulsed laser beam on a solid target. Preformed Molybdenum plasma is created by using Nd:YAG laser pulses with a pulse duration 6 ns and pulse intensity 5.09x1011 W/cm2. Detailed simulations of Ni-like Mo X-ray laser media are undertaken using the EHYBRID code which is a hydrodynamic code. X-ray resonance lines between 25 Å and 40 Å emitted from the molybdenum plasma have been obtained and analysed. EHYBRID code also g...
