Abstract This article presents a parameter optimisation study for the use of an Er:YAG laser in combination with different solvent mixes for the cleaning of a large oil painting on canvas by Jacopo Tintoretto. The painting underwent restoration work between the 1700s and the mid-1900s in which it was lined and some areas were coated with a pigmented protective varnish, which has oxidised over time and has completely obscured the work. Analysis was undertaken in order to study the condition of the work, the painting technique used, and to monitor and verify the effectiveness of the cleaning treatments considered to remove the oxidised varnish. The article reports how the careful calibration and use of cleaning techniques involving the Er:YAG laser and solvent mixes have led to a full recovery of the vibrant chromatic intensity to the pictorial surface of the work.

Er：YAG由Jacopo Tintoretto在威尼斯圣马济阿莱教堂（San Marcoziale）进行的“凯莱的圣马济阿莱”激光清洗

摘要本文针对Jacopo Tintoretto的Er：YAG激光与不同溶剂混合物的组合，用于清洁画布上的大型油画进行了参数优化研究。这幅画在1700年代至1900年代中期进行了衬砌的修复工作，并且在某些区域涂了有色的保护清漆，该保护漆随着时间的流逝被氧化并完全遮盖了工作。进行分析是为了研究工作条件，所用的涂漆技术，以及监测和验证考虑去除氧化清漆的清洁处理的有效性。本文报告了如何仔细校准和使用涉及Er的清洁技术：
