Experimental and theoretical studies of picosecond laser interactions withelectronic materials-laser ablation

摘要

Lasers having picosecond and shorter pulse duration are receiving much attentiondue to their capabilities for direct-write micromachining on many materials with minimal substrate damage. Substantial progress has been made in the understanding of laser ablation processes, particularly the creation of plasmas that often shield the target and reduce the material processing efficiency at nanosecond time scales. However, a considerable challenge that still remains is the understanding of the underlying mechanisms during picosecond laser interactions with electronic solids.
