The generation and interaction dynamics of hot electrons from sub-ps and 10 17 - 10 20W/cm lasers with various thickness of Ti foils, were studied through X-ray spectroscopy in three experiments. The two experiments were carried out with the TARANIS laser at Queen's University Belfast with a second harmonic beam (527mm) and with the fundamental beam (1053mm) in the intensity regime 10 17 - 10 18W/cm. We have observed the Ti K-shell radiation yield correlation with the laser intensity and energy absorption efficiency, and thus confirmed the population and temperature of hot electrons generated as a result of the absorbed energy and laser intensity.
