Abstract

We provide a comparative analysis of representative LWFA regimes driven by Ti:Sapphire and CO2 lasers for realizing a 1-TeV center-of-mass collider. We discuss the technical approach for developing the next-generation ultra-fast CO2 lasers to satisfy requirements of compact linear colliders.

Summary

Plasma wake field accelerators driven with solid-state near-IR lasers have been considered as an alternative to conventional RF accelerators for next-generation TeV-class lepton colliders. Here, we extend this study to the mid-IR spectral domain covered by CO2 lasers. The revealed benefits from such spectral diversification validate our reported ongoing efforts in advancing CO2 laser technology. We discuss the technical approach for developing the next generation of ultra-fast CO2 lasers. We propose new ways for enhanced energy extraction from laser amplifiers and methods to increase the pulse repetition rate to satisfy requirements of compact linear colliders. We provide a comparative analysis of representative LWFA regimes driven by Ti:Sapphire lasers operating in the near-IR and CO2 lasers in mid-IR regimes for realizing a 1-TeV center-of-mass collider. Progress along the route of developing this new laser technology will concurrently benefit other laser applications such as plasma-based compact synchrotron- and THz- radiation sources, laser-driven ion accelerators, among others.
