Abstract
In this paper we will present work in progress in our experimental investigation of the coupling of intense, sub-picosecond laser pulses with plasmas preformed on solid targets. (This situation is to be contrasted with the interaction of intense laser fields with solid-density matter, a subject which has generated considerable interest in the last several years.) We will discuss our characterization of the energy distribution of energetic electrons which escape a solid target irradiated by an intense laser. We have also performed experiments to study the excitation of parametric instabilities near the quarter-critical layer and second-harmonic generation near the critical layer in the plasma. We will discuss some preliminary scattered light spectroscopy measurements. Other topics related to this work are discussed.
