摘要

Plasma based particle accelerators driven by either lasers or particle beams are most probably the future of theparticle accelerators technology. In a laser driven plasma based particle accelerators a stable synchronization ofthe electron bunch and of the plasma wake field in the range of less than 2 fs is necessary in order to optimize theacceleration. For this purpose we are developing a new shot to shot feedback system with a time resolution ofless than 1 fs. As a first step, stable THz pulses are generated by optical rectification of a fraction of the plasmagenerating high energy laser pulses in a nonlinear lithium niobate crystal. It is planed that the generated THzpulses will energy modulate the electron bunches shot to shot before the plasma to achieve the time resolution.In this contribution we systematically investigate the inuence of the optical properties as well as the theoreticaldescription of the THz generation on the conversion effciency of the generation of short THz pulses. We comparedifferent approximations for the modeling of the generation dynamics (full second order calculation or first orderslope varying approximation SVA) and of the dielectric function (linear approximation of the dispersion relation,inuence of the free carries generated by the pump adsorption and their saturation, decreasing of the pumpintensity) in order to investigate the importance of a detailed description of the optical properties.
