Open AccessLaser pulse compression by a density gradient plasma for exawatt to zettawatt lasers
We propose a new method of compressing laser pulses to ultrahigh powers based on spatially varying dispersion of an inhomogeneous plasma. Here, compression is achieved when a long, negatively frequency-chirped...

Open AccessThe role of transient plasma photonic structures in plasma-based amplifiers
High power lasers have become useful scientific tools, but their large size is determined by their low damage-threshold optical media. A more robust and compact medium for amplifying and manipulating intense l...

Open AccessPropagation of intense laser pulses in plasma with a prepared phase-space distribution
Optimizing the laser wakefield accelerator (LWFA) requires control of the intense driving laser pulse and its stable propagation. This is usually challenging because of mode mismatching arising from relativist...

Open AccessHigh-Energy, Short-Duration Bursts of Coherent Terahertz Radiation from an Embedded Plasma Dipole
Emission of radiation from electrons undergoing plasma oscillations (POs) at the plasma frequency has attracted interest because of the existence of intriguing and non-trivial coupling mechanism between the el...

Gamma-rays from harmonically resonant betatron oscillations in a plasma wake
The radiation produced when an intense laser interacts with a solid target could provide a cheaper source of X-rays to synchrotrons and free-electron lasers. But they can also produce short bursts of gamma ray...
