在过去十年中最有前途的技术发展成果之一就是激光。它的应用实际上是无限的并且在任何一个科技领域中这种高度集中的相干光束均能找到自己的应用。眼外科手术,精密测量,成衣业中的裁布,家俱业中的木材切割已经成为司空见惯的事了。保密及高效率的通讯也应用它;这些仅仅是一些民用例子。很多军事应用,如从卫星的跟踪至高精度炮瞄准中的测距已经和它不能分割了。更有吸引力的应用就是正在研究的激光炮（投射器）,它们能破坏正在
One of the most promising technological developments in the last decade is laser. Its application is virtually limitless and its application is found in such a high concentration of coherent light beams in any technological field. Eye surgery, precision measurement, tailoring in the garment industry, and wood cutting in the furniture industry have become commonplace. It is also used by confidential and efficient communications; these are just some examples of civil use. Many military applications, such as ranging from satellite tracking to high accuracy gun sighting, have been unable to segment with it. The more attractive application is the laser cannon (projector) being studied, which can damage the being
