“…Once the required pump energy is reduced to less than ≈1/10, e.g., 50-100 J nanosecond pulses centered at 515/527 nm, the cryogenic gas-cooled diode pumped Yb:YAG lasers can meet the require-ment and importantly which now can operate at 1-10 Hz. [365][366][367] In this case, dramatically reducing pulse duration can realize the high-repetition short-pulse PW laser.…”

The petawatt (PW) laser has experienced a rapid development in the past two decades, and tens of giant facilities have been constructed worldwide. After realizing 10–100 PW, it seems to be close to some sort of engineering limit but its focused peak intensity still is much lower than the Schwinger limit, and therefore some technology improvements or innovations become indispensable for further increasing the peak power as well as the focused peak intensity. By quick reviewing the development of the PW laser in history, it is shown that reducing the pulse duration to near a single optical cycle is a feasible (easy and cheap) choice for this purpose. Here, technologies for the optical‐cycle pulse generation, ultrabroadband amplification, and capability boosting that aim to provide possible approaches for optical‐cycle PW lasers are briefly reviewed and discussed. Meanwhile, key bottlenecks that challenge the current as well as the future short‐pulse PW lasers and their possible solutions are summarized and discussed. This technology review aims to provide a possible roadmap for the next‐stage development of the short‐pulse PW laser.

“…Since the main scientific use of DiPOLE 100-X is laser-driven shock and ramp compression, the laser provides pulse shaping capabilities with a resolution of 125 ps, allowing arbitrary waveforms ranging in duration from 2 to 15 ns. Frequency doubling of the 1030 nm laser to 515 nm with 60 J at 10 Hz for a 10 ns pulse has been demonstrated using a 60 mm large aperture lithium-triborate (LBO) crystal (Phillips et al, 2021); conversion efficiencies for a 2 ns pulse are expected to be similar. The laser is synchronized with the X-ray beam using the XFEL timing system which has an RMS jitter of approximately 10 ps.…”

The European XFEL delivers up to 27000 intense (>1012 photons) pulses per second, of ultrashort (≤50 fs) and transversely coherent X-ray radiation, at a maximum repetition rate of 4.5 MHz. Its unique X-ray beam parameters enable groundbreaking experiments in matter at extreme conditions at the High Energy Density (HED) scientific instrument. The performance of the HED instrument during its first two years of operation, its scientific remit, as well as ongoing installations towards full operation are presented. Scientific goals of HED include the investigation of extreme states of matter created by intense laser pulses, diamond anvil cells, or pulsed magnets, and ultrafast X-ray methods that allow their diagnosis using self-amplified spontaneous emission between 5 and 25 keV, coupled with X-ray monochromators and optional seeded beam operation. The HED instrument provides two target chambers, X-ray spectrometers for emission and scattering, X-ray detectors, and a timing tool to correct for residual timing jitter between laser and X-ray pulses.

“…The dynamic laser compression setup at the HED instrument was conceived for operations in IC2 with the maximum degree of flexibility between the three main components, the DIPOLE 100-X laser, the VISAR velocity interferometer system and the sample station for x-ray diffraction experiments. The DIPOLE 100-X laser [99] is an all diode pumped 100 J class ytterbium:YAG based laser. The VISAR system consists of 3 velocity interferometers at 2 different wavelength (532 and 1064 nm).…”

Synchrotrons and free electron lasers are unique facilities to probe the atomic structure and electronic properties of matter at extreme thermodynamical conditions. In this context, ‘matter at extreme pressures and temperatures’ was one of the science drivers for the construction of low emittance 4th generation synchrotron sources such as the Extremely Brilliant Source of the European Synchrotron Radiation Facility and hard x-ray free electron lasers, such as the European x-ray free electron laser. These new user facilities combine static high pressure and dynamic shock compression experiments to outstanding high brilliance and submicron beams. This combination not only increases the data-quality but also enlarges tremendously the accessible pressure, temperature and density space. At the same time, the large spectrum of available complementary x-ray diagnostics for static and shock compression studies opens unprecedented insights into the state of matter at extremes. The article aims at highlighting a new horizon of scientific opportunities based on the synergy between extremely brilliant synchrotrons and hard x-ray free electron lasers.
