“…When the cleaning efficiency and quality is comparable in both cases (or even better for higher usable laser fluences in the nanosecond case and below the corresponding damage threshold of the object), then also the application of the longer laser pulses can be more reasonable. Figure 20 demonstrates the capabilities of laser cleaning through an optical micrograph that allows directly comparing an untreated soiled silk fabric region (right) with a Nd:YAG ns-laser cleaned silk area (left) [128].…”

Modern life and global communication would not be possible without technologically tailored thin films; they are omnipresent in daily life applications. In most cases, the films are deposited entirely at the carrying substrates in a specific processing step of the device or sample. In some cases, however, removal or modification must be performed locally, i.e., site-controlled and material selective through an additional laser processing step. For that ultrashort laser pulses with durations in the femtosecond and picosecond range can provide unique advantages and capabilities in industrially scalable schemes. This article reviews the current state of the research and corresponding industrial transfer related to the structuring of thin films by ultrashort pulsed lasers. It focuses on the pertinent historic developments, reveals the relevant physical and chemical effects, explores the ultimate limits, and discusses selected industrial and scientific applications.
