The interaction of high intensity laser pulses with underdense plasma is investigated experimentally using a range of laser parameters and energetic electron production mechanisms are compared. It is clear that the physics of these interactions changes significantly depending not only on the interaction intensity but also on the laser pulse length. For high intensity laser interactions in the picosecond pulse duration regime the production of energetic electrons is highly correlated with the…

Generation of quasimonoenergetic electron bunches with 80-fs laser pulses.
The results show that laser-plasma interaction can drive itself towards this type of laser wakefield acceleration even if the initial laser and plasma parameters are outside the required regime.
Particle Acceleration Driven by High-Power, Short Pulse Lasers
The availability of high-power, short-pulse laser systems has created over the last two decades a novel branch of accelerator physics. Laser-driven electron and ion acceleration based on the enormous
Effect of halo on the stability of electron bunches in laser wakefield acceleration
The stability of short electron bunches formed and accelerated by laser wakefield in gas jets strongly depends on parameters of pre-plasma due to poor pulse focus-ability. Instabilities provoked by

The tomographic method adds a crucial dimension to the whole array of existing diagnostics for laser beams, plasma waves, and electron beams by resolving the underlying physical processes in laser-plasma interactions.
Onset of stimulated Raman scattering of a laser in a plasma in the presence of hot drifting electrons
Stimulated Raman scattering of a laser in plasmas with energetic drifting electrons was investigated by analyzing the growth of interacting waves during the Raman scattering process. The Langmuir

Electron acceleration from the breaking of relativistic plasma waves
ELECTRONS in a plasma undergo collective wave-like oscillations near the plasma frequency. These plasma waves can have a range of wavelengths and hence a range of phase velocities1. Of particular
