摘要:

The lifetime of a laser‐induced surface excitation on Al2O3(112̄0) that leads to detectable emission of neutral or positively charged particles and further to optical surface damage is measured to be a ∼200 ps by varying the delay between pairs of 80 ps pulses at 1064 nm. The dependence of the emission threshold fluence on the time delay between laser pulses suggests a low order absorption process.
