Abstract
In order to investigate the similarity on thermo-mechanical effects by different pulsed beams, this paper conducts a comparison study on the blow-off impulse of aluminum target by pulsed ultraviolet laser and X-ray irradiation. Especially, this paper focuses on the thermo-mechanical effects by pulsed ultraviolet laser and X-ray (blow-off impulse), and build up the scaling relations of impulse coupling with aluminum target by the two pulsed beams within a certain range of energy flux. The study shows that, within the energy flux range of 100~400J/cm2, although the mechanisms of blow-off impulse generation of the two pulsed beams are different, the impulse coupling with aluminum target or impulse coupling coefficients of both X-ray and laser have similar scaling relations. Among others, the impulse coupling coefficient of X-ray is larger than that of laser. Based on the comparison of scaling relations, this paper provides the similarity between the two pulsed beams.
