Quasi-monoenergetic electron beams production in a sharp density transition

Quasi-monoenergetic electron beams produced by colliding cross-polarized laser pulses in underdense plasmas

The interaction of two laser pulses in an underdense plasma has been proven to be able to inject electrons into plasma waves, thus providing a stable and tunable source of electrons. Whereas previous works focused on the ‘beatwave’ injection scheme in which two lasers with the same polarization collide in a plasma, this present paper studies the effect of polarization and more specifically the ...

Generation and characterization of quasi-monoenergetic electron beams from laser wakefield

In the interaction of a 30 fs, 40 TW Ti:sapphire Hercules laser focused to the intensity of 1019 W/cm2onto a supersonic He gas jet, we observed quasi-monoenergetic electron beams with energy up to 300 MeV and an angular divergence of 10 mrad. We found that the initial plasma density significantly affects the resultant electron beam. For plasma densities ranging between 2×1019 to 3.5×1019 cm−3, ...

Efficient quasi-monoenergetic ion beams from laser-driven relativistic plasmas.

Table-top laser-plasma ion accelerators have many exciting applications, many of which require ion beams with simultaneous narrow energy spread and high conversion efficiency. However, achieving these requirements has been elusive. Here we report the experimental demonstration of laser-driven ion beams with narrow energy spread and energies up to 18 MeV per nucleon and ∼5% conversion efficiency...
