Comparison of the overall temporal behavior of the bubbles produced by short- and long-pulse nanosecond laser ablations in water using a laser-beam-transmission probe

摘要

We investigate the overall temporal behavior of the bubbles produced by 20-ns- and 100-ns-pulse-duration laser ablations in water using a laser-beam-transmission probe (LBTP). This technique gives the transmission signal attributed to the whole bubble dynamics, including the secondary oscillations, with a single laser shot. Comparing the signals obtained for both pulse durations, the periods of the first oscillation of the bubble are almost the same. Nevertheless, the periods of the subsequent oscillations are significantly different depending on the pulse duration. Such results are obtained by virtue of the LBTP technique.
