激光(Laser)这个词最初是受激辐射光放大(Light Amplification by Stimu-lated Emission of Radiation)这个词组主要词的首字母缩合而成,现在已经使用了二十多年。虽然激光器长时间被认为是一种没有什么用途的器具,但是后来在大量的应用中它已经成为必不可少的东西了。当然,到目前为止,由于种种原因,基本的激光器系统在水下的应用还一直局限于实验性阶段,但是随着激光技术的快速发展和水下作业需求的日 The word laser was originally condensed from the initials of the main word of the phrase Light Amplification by Stimu-lated Emission of Radiation and has now been in use for more than two decades. Although lasers have long been considered a useless instrument, they have become indispensable in a large number of applications later on. Of course, so far, due to various reasons, the basic laser system has been confined to underwater applications in the experimental stage, but with the rapid development of laser technology and underwater operations demand day
