“…On the other hand, self-modulated LWFA [11][12][13][14][15][16][17][18][19][20] normally requires laser pulse lengths substantially longer than 2 ps. Longer pulses allow the wake to grow via Raman forward scattering or a resonant modulation instability within the laser pulse envelope.…”

The upgraded Accelerator Test Facility (ATF) CO 2 laser located at Brookhaven National Laboratory offers a unique opportunity to investigate laser wakefield acceleration (LWFA) with a 10:6-m laser, a wavelength where little experimental work exists. While long laser wavelengths have certain advantages over short wavelengths, our modeling analysis has uncovered another important effect. The upgraded ATF CO 2 laser will have a pulse length as short as 2 ps. At a nominal plasma density of 10 16 cm ÿ3 , this pulse length would normally be considered too long for resonant LWFA, but too short for self-modulated LWFA. However, our model simulations indicate that a well-formed wakefield is nevertheless generated with electric field gradients of E z * 2 GV=m assuming 2.5 TW laser peak power. The model indicates pulse steepening is occurring due to various nonlinear effects. It is possible that this intermediate laser pulse length mode of operation may permit the creation of well-formed, regular-shaped wakefields, which would be needed for staging the LWFA process. Discussed in this paper are the model, its predictions for an LWFA experiment at the ATF, and the pulse steepening effect.

The possibility of producing femtosecond x-rays through Thomson scattering high power laser beams off laser wakefield generated relativistic electron beams is discussed. The electron beams are produced with either a self-modulated laser wakefield accelerator (SM-LWFA) or through a standard laser wakefield accelerator (LWFA) with optical injection. For a SM-LWFA (LWFA) produced electron beam, a broad (narrow) energy distribution is assumed, resulting in X-ray spectra that are broadband (monochromatic). Designs are presented for 3-100 fs X-ray pulses and the expected flux and brightness of these sources are compared.

“…the self-focusing of light in Kerr media is very different in 2D and 3D models so reliable modeling should be three dimensional.. As a result, even the best PIC simulation is limited, in practice, by short simulation times and small plasma volumes which don't match the experimental conditions [11 ]. On the other hand, the disparate sizes of parameters Starting from 3 allows a simplified ,average description [12,13]. the full coupled system of relativistic hydrodynamics for the electron and ion motions and Maxwell's equations, simplified equations for the envelope, averaged over rapidly varying phases, can be derived.…”
