Description

Laser–plasma accelerators (LPAs) can operate in different regimes, namely guided regimes—where laser guiding is achieved by means of an external waveguide such as a plasma channel—and unguided regimes, where the laser is self-guided over the plasma length. For a given (fixed) laser driver energy and wavelength, guided and unguided LPAs exhibit distinct accelerating gradients, stage lengths, optimal bunch parameters, and acceleration efficiencies.

In this talk, we present a systematic investigation of the properties of guided and unguided LPA stages under fixed laser energy and wavelength. We derive and discuss scaling laws for their key characteristics as a function of laser energy and wavelength, and provide estimates of the maximum energy gain achievable with such accelerator stages.
