Abstract Front and rear side x-ray emission from thin titanium foils irradiated by ultraintense laser pulses at intensities up to {approx_equal}5x10{sup 19} W/cm{sup 2} was measured using a high-resolution imaging system. Significant differences in intensity, dimension, and spectrum between front and rear side emission intensity in the 3-12 keV photon energy range was found even for 5 {mu}m thin Ti foils. Simulations and analysis of space-resolved spectra explain this behavior in terms of directional bremsstrahlung emission from fast electrons generated during the interaction process.
