Abstract

Terawatt laser systems based on the chirped-pulse amplification technique readily deliver intense, ultra-short laser pulses, which can be focused down to intensities well above 1017 W·cm−2. Focusing such intense pulses onto solid targets results in the generation of intense, energetic bursts of x-ray radiation1. Unique properties of this x-ray emission have lead to a strong interest in possible radiological applications which cannot be implemented with conventional x-ray tube technology.
