The picosecond evolution of non-Maxwellian electron distribution functions was measured here in a laser-produced plasma using collective electron plasma wave Thomson scattering. During the laser heating, the distribution was measured to be approximately super-Gaussian due to inverse bremsstrahlung heating. After the heating laser turned off, collisional ionization caused further modification to the distribution function while increasing electron density and decreasing temperature. Electron distribution functions were observed using Vlasov-Fokker-Planck simulations including atomic kinetics.
