Underwater production of nano particles by 1064 nm laser ablationon gold and silver targets

摘要

The underwater interaction of 1064 nm laser radiation with silver and gold targets was investigated for the purpose of understanding efficiency of production of nano-particles under laser ablation. Two types of laser pulses were used: the gigantic pulse and the pulse in regime of free generation.rnThe underwater processes of the NIR laser beam-metal target interaction were visualized and measured by applying Mach-Zehnder interference technique.
