“…Sev- eral sub-PW laser systems in the U.S. are also doing significant and important HEP-relevant LPA research. In addition, it is expected that multi-PW, short-pulse laser systems will become available for LPA R&D in the next several years, such as the ZEUS Laser Facility (3 PW) at the University of Michigan [116] and the proposed EP-OPAL laser facility at the University of Rochester [117] that is being designed to produce 2×25 PW beams (20 fs, 500 J, 5 min shot-cycle time) with two target areas supporting a variety of propagation geometries.…”

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...

“…Lithium triborate (LiB 3 O 5 , LBO), with an aperture of approximately 100 mm and a high damage threshold, has supported the OPCPA of multi-PW laser systems centered at 800 nm [9,10] . Deuterated potassium dihydrogen phosphate (KD 2 PO 4 , DKDP) has been proposed in systems exceeding 10 PW, such as SEL, EXCELS and OPAL, due to two advantages: a large aperture of 400 mm [17] and gain bandwidth over 190 nm at the central wavelength of 910 nm [18][19][20] .…”

As optical parametric chirped pulse amplification (OPCPA) has been widely adopted for the generation of extreme intensity laser sources, nonlinear crystals of large aperture are demanded for high energy amplifiers. Yttrium calcium oxyborate (YCa 4 O(BO 3 ) 3 , YCOB) is capable to be grown with aperture exceeding hundred millimeters, which makes it possible for application in systems of petawatt scale. In this paper, we experimentally demonstrated for the first time to our knowledge, an ultrabroadband non-collinear optical parametric amplifier with YCOB for petawatt scale compressed pulse generation at 800 nm. Based on SG-Ⅱ 5PW facility, amplified signal energy of ~40 J was achieved and pump-to-signal conversion efficiency was up to 42.3%.A gain bandwidth of 87 nm was realized and supported compressed pulse duration of 22.3

Stability improvement of multi-beam picosecond–petawatt laser system for ultrahigh peak-power applications

et al. 2023

Pointing fluctuations of beams reduce the possibility of incoherent or coherent addition for ultrahigh peak power in a multi-beam picosecond–petawatt laser system. Pointing fluctuations on the target were observed on Shenguang Upgrade Petawatt (SGII-UP-Petawatt) beam using a high-speed and high-resolution active pointing stabilization control system. The maximum frequency of the pointing fluctuations was less than 50 Hz, and the amplitude was approximately 2.8 µrad (RMS). An online test of pointing fluctuations with active stabilization control demonstrated that pointing fluctuations could be reduced to 0.63 µrad (RMS), approximately one-quarter of that without active stabilization control. The benefits of reduced pointing fluctuation were estimated using a multi-beamlet petawatt laser system; the results demonstrated that peak power could be increased by 51.7% when active stabilization control was used in an eight-beamlet picosecond–petawatt laser system.
