Abstract

Highly ionized aluminium plasmas created using long (nanosecond) and short (picosecond) duration laser pulses are studied using a combination of high resolution X-ray spectroscopy and computational modeling tools. The experiments are designed to be simple and the emission spectra well characterized so that detailed observation of strong, single frequency electric fields effects can be observed and studied. Strong oscillating electric fields can modify the emission spectra of ions by altering spectral line shapes, through ionization processes, and the appearance of field-induced satellite lines. However, field-induced effects are expected to be weak, thus high dispersion, high luminosity spatially resolving spectrometers are employed. Initial results are discussed and an example of a possible field induced modification of a spectral line shape is presented.
