Cavity-free lasing of Nitrogen and laser gain without population inversion
The blue “air laser”, or more specifically the lasing emission at 391 nm from remotely excited ionized nitrogen molecules, has […]
Long term stability of a kHZ laser-plasma accelerator
Laser-plasma acceleration enables the generation and acceleration of electrons beams over very short distances due to extreme longitudinal accelerating fields, […]
Phase-locked laser-wakefield electron acceleration
A Laser-Plasma Accelerator (LPA) uses accelerating fields (wakefield) that are typically 3 orders of magnitude higher than in radio-frequency accelerators. […]
Two color soft x-ray laser
X and soft X-ray coherent sources are widely used tools to probe ultrafast dynamics of the matter on the nanometer […]

Relativistic-intensity 1.5-cycle light waveforms at kHz repetition rate
The development of ultra-intense and ultra-short light sources is currently a subject of intense research driven by the discovery of […]
Structured Plasma Boosts X-Ray Flux
High-intensity sources of femtosecond x-ray pulses are a must-have tool for studying ultrafast processes. Unfortunately, only a handful of kilometer-long […]
