چکیده
Abstract Large scale laser facilities are needed to advance the energy frontier in high physics and accelerator physics. Laser plasma accelerators core advanced concepts aimed at reaching TeV electron colliders. In these facilities, intense pulses drive plasmas used accelerate electrons energies remarkably short distances. A could principle reach with an accelerating length that is 1000 times shorter than conventional RF based accelerators. Notionally, driven particle beam beyond state of art LPAs have produced multi GeV beams about 20 cm relative spread 2 percent, supported by highly developed technology. This validates key elements US DOE strategy for such enable future colliders but extending best results date a collider will require lasers higher average power. While per pulse envisioned achievable current lasers, low repetition rates limit potential luminosity. Applications kHz tens Joules efficiency, would 100 stages, leap from Hz class LPAs. represents challenging fold increase art. whitepaper describes research outlook candidate systems as well accompanying broadband damage threshold optics driving

High-efficiency, single-stage 7-kHz high-average-power ultrafast laser system.
We demonstrate a simple and practical single-stage ultrafast laser amplifier system that operates at a repetition frequency from 1 to 10 kHz, with millijoule pulse energy and as much as 13 W of average power. The repetition rate can be adjusted continuously from 1 to 10 kHz by new all-solid-state pump laser technology. This is to our knowledge the highest average power ever obtained from a sing...
متن کاملHigh energy and average power femtosecond laser for driving mid-infrared optical parametric amplifiers.
We have developed the first (to our knowledge) femtosecond Tm-fiber-laser-pumped Ho:YAG room-temperature chirped pulse amplifier system delivering scalable multimillijoule, multikilohertz pulses with a bandwidth exceeding 12 nm and average power of 15 W. The recompressed 530 fs pulses are suitable for broadband white light generation in transparent solids, which makes the developed source ideal...
متن کاملHigh sustained average power cw and ultrafast Yb:YAG near-diffraction-limited cryogenic solid-state laser.
We report what we believe to be record performance for a high average power Yb:YAG cryogenic laser system with sustained output power. In a CW oscillator-single-pass amplifier configuration, 963 W of output power was measured. In a second configuration, a two amplifier Yb:YAG cryogenic system was driven with a fiber laser picosecond ultrafast oscillator at a 50 MHz repetition rate, double-passe...
