Laser-plasma accelerators are capable of sustaining accelerating fields of 10–100 GeV/m, 100–1000 times that of conventional technology and the highest fields produced by any of the widely researched advanced accelerator concepts. Laser-plasma accelerators also intrinsically accelerate short particle bunches, several orders of magnitude shorter than that of conventional technology, which leads to reductions in beamstrahlung and, hence, savings in the overall power consumption to reach a desired luminosity. These properties make laser-plasma accelerators a promising accelerator technology for a more compact, less expensive high-energy linear collider providing multi-TeV polarized leptons. In this submission to the Snowmass 2021 Accelerator Frontier, we discuss the motivation for a laser-plasma-accelerator-based linear collider, the status of the field, and potential linear collider concepts up to 15 TeV. We outline the research and development path toward a collider based on laser-plasma accelerator technology, and highlight near-term and mid-term applications of this technology on the collider development path. The required experimental facilities to carry out this research are described. We conclude with community recommendations developed during Snowmass.

“…Industrial ultrafast laser sources providing multi-kilowatts of average powers and several tens-of-millijoules pulse energies will be available soon (Sutter et al, 2019;Dominik et al, 2021;Mans et al, 2021;Dominik et al, 2022). These laser systems enable the development of completely new application strategies, such as, e.g., single-pass, millimeter-scaled cutting of glasses with m/s-feed rates (Hosseini and Herman, 2016;Jenne et al, 2020).…”

A structured light concept is reported enabling to distribute a large number of focus copies at arbitrary positions in a working volume. Applying this holographic 3D-beam splitter concept to ultrashort laser pulses allows to deposit energy along accelerating trajectories in the volume of transparent materials. Based on the entirety of the volume modifications created in this way, the material can be separated, for example, to create chamfered glass edges. These photonic tools impress with enormous versatility, which enable equally diverse application strategies ranging from cutting and welding to data storing.

“…Over the long term, the development of reliable, high-rep-rate sources in the mid-wave infrared (3-8µm) and long-wave infrared (8-15 µm) could also provide unique opportunities for HEP applications, including as an enabling technology for an "all-optical" source of highbrightness, potentially spin-polarized, electron beams using two-color injection [42,43,64]. Other promising paths include using diode-pumped, cryogenically-cooled, thin-disk Yb:YAG or Tm:YLF as amplifier gain media [65][66][67][68], combined with nonlinear pulse compression technologies [69,70], or novel, plasma-based methods for modulating ps-duration pulses [71]. All candidate laser technologies require development of active control techniques for laser precision and stability [72,73], and high peak and average power handling optics, including compression gratings [74,75] and robust optical coatings [76][77][78].…”

Laser-plasma accelerators (LPAs) are capable of sustaining accelerating fields of 1-100 GeV/m, 10-1000 times that of conventional RF technology, and the highest fields produced by any of the widely researched advanced accelerator concepts. Furthermore, LPAs intrinsically produce short particle bunches, 100-1000 times shorter than that of conventional RF technology, which leads to reductions in beamstrahlung and savings in overall power consumption. Furthermore, they enable novel energy recovering methods that can reduce power consumption and improve the luminosity per unit energy consumption for linear colliders. These properties make LPAs a promising candidate as drivers for a more compact, less expensive high-energy collider by providing multi-TeV polarized leptons in a relatively short distance ∼1 km. Collider concepts are discussed up to the 15 TeV range. A future RF-based linear collider facility could be re-purposed to delivery higher energies with LPA technology thereby extending physics reach while saving on construction costs.Previous reports have made strong recommendations for a vigorous program on LPA R&D and applications, including the previous P5 and subcommittee reports, the European Strategy and Laboratory Directors Group reports, and several others. Numerous significant results have been obtained since the last P5 report, including the production of high quality electron bunches at 8 GeV from a single stage, the staging of two LPA modules, novel injection techniques for ultra-high beam brightness, investigation of processes that stabilize beam break up, new concepts for positron acceleration, and new technologies for high-average-power, high-efficiency lasers. In addition to the long term goal of a high energy collider, LPAs can provide compact sources of particles and photons for a wide variety of near-term applications in science, medicine, and industry.Research on LPAs has exploded in recent years, driven in part by the extremely rapid advances made in high-power lasers based on the 2018 Nobel Prize winning technique of chirped-pulse amplification. Numerous high-power laser facilities have sprung up worldwide, particularly in Europe and Asia. Consequently, about 800-1000 research papers are published annually on LPAs. Since much of this research is overseas, it is critical that the U.S. make strong investments in LPAs to ensure global leadership.The LPA community proposes the following recommendations to the Snowmass conveners:1. Vigorous research on LPAs, including experimental, theoretical, and computational components, continue as part of the General Accelerator R&D program to make rapid progress along the LPA R&D roadmap towards an eventual high energy collider, develop intermediate applications, and ensure international competitiveness.2. Enhance R&D on laser drivers to develop the efficient, high repetition rate, high average power laser technology that will power LPA colliders.3. Near-term LPA capability extensions should be carried out, such as enhancing existing facilities in laser pe...
