phase explosion and its time lag in nanosecond laser ablation

phase explosion and its time lag in nanosecond laser ablation
... Hence, explosive phase change occurs, which turns the liquid into a mixture of liquid and vapor One important factor in analyzing phase change induced by pulsed laser heating is the time required ... a critical nucleus This time is also called the time lag for nucleation The time lag must be considered in pulsed laser ablation since it is on the same order of the laser pulse duration Eq (2) ... higher than 5.2 J/cm2 can be explained in terms of the time lag for phase explosion As discussed previously, before phase explosion can take place, there is a certain time needed for a vapor embryo...
