“…These disks are pumped from both sides by diode lasers and cooled using a flow of helium gas cooled by liquid nitrogen; see Figure 6(a). More recently, new schemes based on lasing media with broadband amplification and large energy storage, such as thulium-doped crystals [ 92 ] or ceramics [ 93 ] , have been proposed and are being investigated at LLNL and ILIL laboratory at CNR, among the others, and provide an entirely new platform for high-efficiency amplification. Crucial for developing these systems is the availability of efficient and robust diode laser stacks capable of high-duty cycle operation and long lifetime.…”

The recent achievement of fusion ignition with laser-driven technologies at the National Ignition Facility sets a historic accomplishment in fusion energy research. This accomplishment paves the way for using laser inertial fusion as a viable approach for future energy production. Europe has a unique opportunity to empower research in this field internationally, and the scientific community is eager to engage in this journey. We propose establishing a European programme on inertial-fusion energy with the mission to demonstrate laser-driven ignition in the direct-drive scheme and to develop pathway technologies for the commercial fusion reactor. The proposed roadmap is based on four complementary axes: (i) the physics of laser–plasma interaction and burning plasmas; (ii) high-energy high repetition rate laser technology; (iii) fusion reactor technology and materials; and (iv) reinforcement of the laser fusion community by international education and training programmes. We foresee collaboration with universities, research centres and industry and establishing joint activities with the private sector involved in laser fusion. This project aims to stimulate a broad range of high-profile industrial developments in laser, plasma and radiation technologies along with the expected high-level socio-economic impact.

“…This implies that different laser technologies and amplifying media may be considered for a laser-plasma-based collider. Two potential technologies that could achieve the required peak and average laser power are coherent combination of fiber lasers [17,18], operating at 𝜆 1 μm, and lasers based on Tm:YLF [19], operating at 𝜆 1.9 μm.…”

Beam dynamics challenges in linear colliders based on laser-plasma accelerators

In this paper we discuss design considerations and beam dynamics challenges associated with laser-driven plasma-based accelerators as applied to multi-TeV-scale linear colliders. Plasma accelerators provide ultra-high gradients and ultra-short bunches, offering the potential for compact linacs and reduced power requirements. We show that stable, efficient acceleration with beam quality preservation is possible in the nonlinear bubble regime of laser-plasma accelerators using beam shaping. Ion motion, naturally occuring for dense beams (i.e., low emittance and high energy) severely damps transverse beam instabilities. Coulomb scattering by the background ions is considered and it is shown that the strong focusing in the plasma strongly suppresses scattering-induced emittance growth. Betatron radiation emission from the transverse motion of the beam in the plasma will result in beam power loss and energy spread growth; however for sub-100 nm emittances, the beam power loss and energy spread growth will be sub-percent for multi-TeV-class plasma linacs.
