Laser Cleaning II is the second of a series of books reporting research on the use of lasers for cleaning material surfaces and related micro-scale and nano-scale laser processing. It follows Laser Cleaning, edited by Boris Luk’yanchuk, published in 2002. The primary focus is on contaminant particle removal, nano-scale sized particles in particular, which represents a major cleaning challenge in industrial contexts and poses a broad range of research questions. The contributions provide stimulating answers to these questions, spanning the essential areas: the fundamental theoretical and experimental physics of light/particle/interface interactions, invention and development of laser cleaning techniques and diagnostics, simulations for important material and process systems, and laser cleaning and processing applications. Laser cleaning for art and cultural heritage conservation is a related, mature field of research which is also treated.
