This contribution deals with observations of relativistic electrons produced in a laser plasma interaction experiment at the PALS laser system operated at the Institute of Plasma Physics in Prague. The PALS laser is a near-infrared 3-TW iodine laser designed to deliver irradiance on target of 1016 Wcm-2 in ~300 ps pulses at the wavelength of 1.315 μm. Various foils of 6 – 500 μm in thickness were irradiated with Iλ2 ~5x1016 Wcm2μm2. Under these conditions we have observed relativistic electrons expanding into the vacuum with maximum energy going beyond 4 MeV. The observed electron energy spectra indicate that the applied laser intensity was increased by the thermal and relativistic self-focusing. The application of a unique femtosecond interferometry technique allowed us to observe bunches of thermal electrons occurring in the plasma expanding against the focused laser beam.
