Relativistic interaction of short-pulse lasers with underdense plasmas has recently led to the
emergence of a novel generation of femtosecond x-ray sources. Based on radiation from …

Laser-wakefield accelerators (LWFAs) were proposed more than three decades ago, and
while they promise to deliver compact, high energy particle accelerators, they will also …

Laser-driven plasma-based accelerators, which are capable of supporting fields in excess of
100 GV∕ m, are reviewed. This includes the laser wakefield accelerator, the plasma beat …

Research into terahertz technology is now receiving increasing attention around the world,
and devices exploiting this waveband are set to become increasingly important in a very …

Gigaelectron volt (GeV) electron accelerators are essential to synchrotron radiation facilities
and free-electron lasers, and as modules for high-energy particle physics. Radiofrequency …

Laser-driven plasma accelerators provide acceleration gradients that are three orders of
magnitude greater than those generated by conventional accelerators, offering the potential …

Organic π‐conjugated crystals with second‐order optical nonlinearity are considerably
attractive materials for diverse terahertz (THz) wave photonics. An overview of the research …

Particle accelerators driven by the interaction of ultraintense and ultrashort laser pulses with
a plasma can generate accelerating electric fields of several hundred gigavolts per metre …

Plasma-based accelerators that impart energy gain as high as several GeV to electrons or
positrons within a few centimeters have engendered a new class of diagnostic techniques …

We report the generation of MeV x rays using an undulator and accelerator that are both
driven by the same 100-terawatt laser system. The laser pulse driving the accelerator and …
