Abstract

Abstract

We have developed a high-power near-single-cycle laser source at kHz repetition rate in order to steer relativistic laser-plasma interactions on the sub-cycle time scale. With this system, we demonstrate laser-driven electron acceleration in gas jets and intense attosecond pulse generation from plasma mirrors.

Abstract

Abstract

Two pressing demands in our western society are illicit traffic of SNM and maintenance of our nuclear legacy. Neutrons are a tool in non-destructive testing and inspection of complex objects. We have demonstrated a laser-driven neutron source with intensities orders of magnitude above earlier attempts that lead to a large number of applications. I present mechanism, applications and recent experimental results using laser systems in the US and Europe.

Abstract

Abstract

Measurements of the ultrafast energy deposition occurring during ultrashort pulse laser filamentation will be presented. These spatially
resolved measurements of single filaments are examined as a function of various laser parameters and applied to investigations of high-voltage spark gap dynamics.

Abstract

Abstract

Extreme nonlinear optics of gaseous media is an interdisciplinary branch of applied physics motivated by various potential applications. I will discuss two of them: air lasing and channeling the dielectric breakdown of air. Both applications benefit from recent developments in ultrafast laser technology.

Abstract

Abstract

Laser driven plasma waves enable compact accelerators. Energies to 7.8 GeV were achieved in 20cm, and multi-GeV staging is being prepared towards future colliders. Compact photon source applications include FELs and MeV Thomson scattering. Laser development is important for high repetition rate and precision.
