This project will develop a novel laser cleaning system for artwork conservation. Lasercleaning is an extremely controllable and sensitive method of removing unsightly andpotentially damaging pollution encrustations, paint layers, corrosion layers and otherunwanted surface accretions from works of art and other heritage objects. The vast majority oflaser cleaning systems deliver laser radiation at a wavelength of 1064nm, which is ideal forhigh quality cleaning of a wide range of materials, including: marble, limestone, sandstone,terracotta and plaster. This project will focus on developing a laser handpiece, compatiblewith Lynton Lasers Compact Phoenix system, to deliver laser radiation at 2940nm for treatingartefacts which cannot be cleaned satisfactorily using laser radiation at 1064nm or by moretraditional methods of cleaning. Such layers include old discoloured varnish layers frompaintings, organic substances from stone carvings and corrosion layers from archaeologicalmetal artefacts. The development of a novel hybrid 1064/2940nm laser cleaning system wouldbe a world first, making Lynton Lasers’ Compact Phoenix system the most versatile lasercleaning system currently available for conservation.

本项目将开发一种用于艺术品保护的新型激光清洗系统。激光清洗是一种非常可控和敏感的方法，可以去除艺术品和其他遗产物品上不美观和潜在破坏性的污染结壳、油漆层、腐蚀层和其他不需要的表面堆积。绝大多数激光清洗系统提供波长为1064nm的激光辐射，这是各种材料高质量清洗的理想选择，包括：大理石，石灰石，砂岩，陶土和石膏。该项目将重点开发与Lynton激光器紧凑型凤凰系统兼容的激光机头，提供2940nm的激光辐射，用于处理使用1064nm激光辐射或更传统的清洁方法不能令人满意的工件。这些层包括油画上旧的变色清漆层、石雕上的有机物质和考古金属制品上的腐蚀层。新型混合1064/2940nm激光清洗系统的开发将是世界首创，使林顿激光公司的紧凑型凤凰系统成为目前可用于保护的最通用的激光清洗系统。
