Abstract Text:
The generation of high harmonics from solid surfaces [1-3] offers the prospect of generating attosecond bursts of XUV and soft X-ray radiation orders of magnitude more intense than those generated from gaseous media. Such pulses would, for the first time, enable researchers to explore a whole new class of attosecond time resolution XUV-pump XUV-probe type experiments. In addition the harmonic emission opens the possibility of directly probing surface properties and density of overdense plasmas on femtosecond timescales.
In this talk recent results pertaining to both of these objectives will be shown. We present the first direct experimental observation of a train of attosecond pulses from the interaction of a relativistically intense laser pulse with a solid target [4] and demonstrate that the harmonic beam emitted from the target can be used to probe the density [5] and surface properties of solid density plasmas [6-8] on the femtosecond time scale.
Our observations demonstrate that high harmonics generated from solid density plasmas are indeed a very versatile tool spanning a wide range of possible applications from attosecond physics to in situ probing of dense plasmas on ultrafast timescales.
