controlling phase change through ultrafast excitation of coherent phonons

... materials damage was investigated in this work. The damaged areas produced by 5,000 pulses were measured. Using 5,000 pulses instead of single pulse allows determination of the damage areas ... excitation can be caused by the differences in the fluences of the individual pulses - the fluences of the individual pulses in the two-pulse pulse train are higher. In...
