Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the final finish is achieved. We will research this technique for application to unique Australian heritage materials that are important to the specific conservation needs of the Australian War Memorial, the RAAF, Navy and Army Museums, Artlab Australia, and the Art Gallery of NSW.

保护遗产是一门要求很高的学科，需要一套技术来解决不同的问题。 在国外，使用长脉冲技术的激光清洗会在去除离散的材料块时留下微观损伤，并且不适合许多材料。 我们开发了一种短脉冲激光工艺，可以以受控方式逐个分子地去除材料，并且一旦完成最终表面处理就可以轻松停止。 我们将研究这项技术，以应用于独特的澳大利亚遗产材料，这些材料对于澳大利亚战争纪念馆、澳大利亚皇家空军、海军和陆军博物馆、澳大利亚艺术实验室和新南威尔士州美术馆的特定保护需求非常重要。
