A case study was performed for laser cleaning of a soiled First Phase Navajo chief 's blanket using the first and second harmonics of a Nd:YAG laser. A cleaning protocol was developed by mapping the impact of wavelength, fluence, pulse number, and surface pre-wetting on churro wool reference samples. Afterward, an approach for applying the protocol to the Navajo blanket was developed, including a number of custom jigs for mounting the object under controlled tension. The most effective laser cleaning parameters were determined to be a wavelength of 532 nm, a fluence of 350mJ/cm 2 , approximately 100 pulses per cross-sectional area of the laser beam, and no pre-wetting. Good results with no observable damage were obtained with ~280 hours of laser cleaning for the entire blanket, which measured 138 cm by 208 cm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
