Self-modulated wakefield and forced laser wakefield acceleration of electrons
The interaction of intense laser pulses (power.30 TW) with underdense plasmas has been studied. In the regime where the pulse length is much longer than the plasma period (t l@2pvp ), the laser pulse is found to be self-modulated at the plasma frequency by the forward Raman scattering instability. Wavebreaking of the resulting plasma wave results in energetic electrons being accelerated to more...
متن کاملSelf-guided laser wakefield acceleration beyond 1 GeV using ionization-induced injection.
The concepts of matched-beam, self-guided laser propagation and ionization-induced injection have been combined to accelerate electrons up to 1.45 GeV energy in a laser wakefield accelerator. From the spatial and spectral content of the laser light exiting the plasma, we infer that the 60 fs, 110 TW laser pulse is guided and excites a wake over the entire 1.3 cm length of the gas cell at densit...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولQuasi-phase-matched laser wakefield acceleration.
The energy gain in laser wakefield acceleration is ultimately limited by dephasing, occurring when accelerated electrons outrun the accelerating phase of the wakefield. We apply quasi-phase-matching, enabled by axially modulated plasma channels, to overcome this limitation. Theory and simulations are presented showing that weakly relativistic laser intensities can drive significant electron ene...
متن کاملInjection, trapping, and acceleration of electrons in a three-dimensional nonlinear laser wakefield
It is demonstrated that the accelerating and focusing phases of the nonlinear three-dimensional axisymmetric laser wake can almost entirely overlap starting from a certain distance behind the laser pulse in homogeneous plasma. Such field structure results from the curvature of phase fronts due to the radially inhomogeneous relativistic shift of plasma frequency. Consequently, the number of trap...
