摘要：

We have studied ablation plumes generated by femtosecond and picosecond-laser pulses using various optical methods for both single-pulse ablation as well as for drilling with up to 1 kHz repetition rate. Time-resolved shadow and resonance-absorption photographs visualize the plume- and vapor-expansion behavior in the nanosecond- and microsecond-time domains whereas the detection of Mie-scattered 308 nm-radiation allows to qualify the vapor movement and accumulation up to several milliseconds, i.e. well beyond the corresponding pulse-to-pulse separation at 1 kHz repetition rate.
