Due to the pump-probe femtosecond resolution of the measurements, the plasma dynamics was observed, along with the pump pulse propagation. The effects of impact ionization and recombination were evidenced during the plasma evolution up to hundreds of picoseconds. This measurement system will integrate our laboratory infrastructure as a key tool for diagnosing gas targets and laser-target interaction in laser wakefield acceleration experiments.C128-C134openAccessArtigo de periódico86210.1364/AO.4773950000-0001-7762-89610000-0003-0092-9357https://orcid.org/0000-0001-7762-8961https://orcid.org/0000-0003-0092-935731.556.00
