Resumo
Laser particle acceleration is a rapid growing
field due to the compactness and smaller cost when compared
to traditional accelerators, as well as the potential for new
applications resulting from the unique characteristics of the
beams generated. Frequently, laser acceleration techniques
require laser intensities higher than 100's of PW/cm2 and highdensity
gas targets, with specific profiles. In the effort to
implement laser electron acceleration in our laboratories, we
report the development of submillimetric, supersonic gas
nozzles, the implementation of optical techniques for the
determination of the gas jets density profiles, and the
characterization of laser-induced plasmas obtained at laser
intensities surpassing 1016 W/cm2. The characterization
techniques employed include plasma spectroscopy,
interferograms and Schlieren images.
