Comprehensive investigation of laser energy transport to a massive planar targets with femtosecond polaro-interferometry

Original language description

The paper is a continuation of the space-time resolved spontaneous magnetic fields (SMF) measurements performed on PALS (Prague Asterix Laser System) [1]. To measure SMF distributions with high temporal resolution, two-channel polaro-interferometer irradiated by the Ti:Sa laser pulse, with the wavelength of 808 nm and the pulse duration of 40 fs was used. The experiments were performed by using the 1omega single laser beamn(1.315 micro m) with the linear and the circular polarization, focused to the focal spot radius RL=50 micro m and interacted with the Cu planar massive target. The primary goal was to understand the interrelation between spontaneous magnetic field (SMF) creation and fast electron generation in laser plasma produced from Cu planar massive targets.nObtained space-time distributions of SMF was used to calculate current density distributions and the energy deposited in the magnetic field of the ablative plasma and to estimate the electron energy for different expansion times during the laser-target interaction. Additionally, measurements of the total current through the target were carried out with current probes. The calculated from SMF distribution electron spectra in the expanding plasma were also compared to the electron spectra obtained by the magnetic electron spectrometer
