在制造业，特别是在航空制造业中，各种产品零件在装配前需要进行认真仔细的去脂除污处理，传统的清洗方法有很多种。随着环境保护、高精度以及高效率的矛盾日显突出，各种有利于环境保护、适合于超精加工领域零件的清洗技术应运而生，激光清洗技术就是其中之一。介绍了激光清洗技术的原理和方法，研究了利用脉冲Nd:YAG激光清洗被污零件的情况，对研究结果进行了讨论。并对激光清洗技术的应用前景进行了展望。

In manufacturing industry, especially in aviation manufacturing industry, there are many traditional cleaning methods for decontaminating all kinds of product components before assembling. But along with the restricted requirement of environmental protection, as well as the high accuracy and high efficiency, many existing cleaning technology are not suitable for it. Some new kinds of cleaning technology with environment friendly become available nowadays in ultraprecision machining domain. The laser cleaning technology is one of them. The principle and the method of the laser cleaning technology are introduced, and the application of pulse Nd:YAG laser to clean the contaminated parts is researched. The results of the experiment are discussed. Futhermore, the future of cleaning technology is predicted.
