Paper Abstract

Splash generation and evolvement have been observed with ns-shadowgraphy time resolved method on the laser micro ablation with liquid working substance. The flow visualization method of splash phenomenon is introduced and the shock wave and particle front velocity were measured and analyzed to research the relationship between material characteristics and splash dynamics. Three different laser energy densities and four different doped mass fractions are adopted for the comparison to find out the energy intensity density and work substance doped mass fraction influence on the splash generation and evolvement. The results show that: the carbon doped in the liquid working substance could weaken the splash process with the smaller droplets and shorter duration time.
