Formation of high-aspect-ratio protrusions on gold films by localized pulsed laser irradiation

We report on the formation of microbumps and high-aspect-ratio protrusions on gold films as a result of single-pulse localized laser irradiation. The laser source employed in this work is a Q-switched nanosecond-pulse laser, emitting at its fourth harmonic of 266 nm. Gold films with a thickness of s...
