Cryogenic Composite Disk Laser for Peak and Average Power Scaling

Luis E. Zapata

Abstract: Abstract:We demonstrate high gain producing 60 mJ, 200 ps pulses at 200 Hz from a single 4-mm ASE limited gain-cell. A scaling paradigm utilizing a monolithic array of gain cells is proposed.

“…The accelerating gradient in the THz structures demonstrated in this work can be as high as GeV/m with a single cycle THz pulse of 10 mJ (See Methods: THz LINAC), which can be readily produced by a 250 mJ IR pulse when using optimized THz generation 14 . Laser systems producing such and even higher energy ps pulses with up to kHz repetition rates are on the horizon 24 .…”

The cost, size and availability of electron accelerators are dominated by the achievable accelerating gradient. Conventional high-brightness radio-frequency accelerating structures operate with 30–50 MeV m−1 gradients. Electron accelerators driven with optical or infrared sources have demonstrated accelerating gradients orders of magnitude above that achievable with conventional radio-frequency structures. However, laser-driven wakefield accelerators require intense femtosecond sources and direct laser-driven accelerators suffer from low bunch charge, sub-micron tolerances and sub-femtosecond timing requirements due to the short wavelength of operation. Here we demonstrate linear acceleration of electrons with keV energy gain using optically generated terahertz pulses. Terahertz-driven accelerating structures enable high-gradient electron/proton accelerators with simple accelerating structures, high repetition rates and significant charge per bunch. These ultra-compact terahertz accelerators with extremely short electron bunches hold great potential to have a transformative impact for free electron lasers, linear colliders, ultrafast electron diffraction, X-ray science and medical therapy with X-rays and electron beams.
