The Zettawatt Equivalent Ultrashort pulse laser System (ZEUS) is a National Science Foundation-funded user facility housed at the University of Michigan. The laser will be capable of producing 3-Petawatt pulses, or may be split to create synchronized 2.5-PW and 0.5-PW pulses. The first user experiments are due to begin in late 2023. This presentation will describe the different capabilities of...

Pavel Bakule (ELI Beamlines Facility, Extreme Light Infrastructure ERIC)9/18/23, 4:45 PMWG2: Laser technologyOral contribution
L1 ALLEGRA system has been regularly and reliably operating for user experiments offering over 20 weeks of user beamtime per year. The laser generates 15 fs pulses with energy of up to 50 mJ and repetition rate of 1 kHz. Since the laser is completely based on OPCPA pumped by 3 ps pulses, it has inherently very high picosecond temporal contrast. The output pulse energy is limited by the...

The laser system “Bivoj” built on “DiPOLE” cryogenically cooled multi-slab technology (150J / 10Hz / 10ns) has been enhanced by a conversion module for second harmonic frequency generation (95J/10Hz @515nm) with 79% conversion efficiency. This allows the laser to be used as a pump source for short pulse beamlines (CPA or OPCPA) that can be used for efficient particle acceleration. Achieving...

Dr Luca Labate (Consiglio Nazionale delle Ricerche, Istituto Nazionale di Ottica, Pisa, Italy)9/18/23, 5:45 PMWG2: Laser technologyOral contribution
Scaling current ultrashort/ultraintense laser technology, based on Nd-pumped TiSa amplifiers, to the rep-rate and average power required for future laser-driven electron accelerators is ultimately hindered by wall plug efficiency. One of the paths currently pursued to overcome the limits of TiSa technology is based on the usage of long ($\sim\mathrm{ms}$) upper state lifetime materials that...

Andrea Knigge (Ferdinand-Braun-Institut)9/18/23, 6:05 PMWG2: Laser technologyOral contribution
Diode laser pumps are a critical technology for advanced accelerators based on plasma acceleration, and essential system components when higher repetition rate operation is needed. They are a significant cost element in larger systems, and there is only a limited number of commercial suppliers who can support the needs of emerging systems and applications.

The possibilities for experimental research on laser-particle acceleration strongly depend on the available laser and laboratory infrastructure. The Helmholtz-Institute Jena and the Institute of Optics and Quantum Electronics in Jena, Germany, currently operate two individual high-power laser systems (JETI and POLARIS), which differ in their laser parameters. In the future, these two laser...

Here we give a brief overview of the development of DPSSL-based high-average power laser drivers for plasma accelerators in CLF. We will describe the design of the Extreme Photonics Applications Centre (EPAC): a unique facility dedicated for the exploitation of the applications of plasma accelerators. Future upgrade paths for EPAC, especially in repetition rate, would be discussed.

The kilohertz Plasma Accelerator Consortium (kPAC) is developing GeV-scale, laser-driven plasma accelerators, utilizing highly efficient, diode-pumped lasers with kHz repetition rate. The concept is based on the plasma-modulated plasma accelerator (P-MoPA). In such an accelerator, a joule-class pulse with picosecond duration is first spectrally modulated by the wake of a second,...
