一、前言 激光技术的研究和推广应用的水平,是标志一个国家现代化程度的高级技术之一。十年之前,激光技术还只是作为一项寻求应用的发明,而今形势却发生了巨大的变化。目前它的应用已广泛深入到科学研究和工业范围中的许多领域。从激光技术本身发展来看,它的应用研究及其的理论和设备几乎是同步发展。它的发展速度之快,可以与计算机前三十年的发展速度相媲美(图1)。激光 I. Introduction The level of laser technology research and promotion and application is one of the advanced technologies that mark the degree of modernization of a country. Ten years ago, laser technology was only used as an application for invention, but the situation has changed dramatically. Its use has now been extensively studied in many areas of scientific research and industry. From the development of laser technology itself, its application and its theory and equipment is almost simultaneous development. Its speed of development is comparable to that of the first three decades of computing (Figure 1). laser
