前言激光是六十年代发展起来的一门尖端技术。由于它的引人注目的特点;如亮度极高,方向性、单色性和相干性好等,因此,在国防建设、工农业生产以及科学实验等各方面都得到了极为广泛的应用。特别是七十年代蓬勃发展起来的海洋遥感技术,为激光在海洋学上的应用开辟了广阔的道路,对海洋学的发展产生了较大的推动作用。激光在海洋研究上的应用也象在其他领域的应用一样,已经在短时间内取得很大的进展。目前已成功地利用激光进行水下探测和通讯。用机载激光器遥测海洋表层和次表层的海洋物理要素;探测海洋水深和绘制浅海海底地形图。此外正在探索利用激光荧光和喇曼光谱 Introduction Laser is a cutting-edge technology developed in the sixties. Due to its striking features such as high brightness, good directivity, monochromaticity and good coherence, it has been widely used in various fields such as national defense construction, industrial and agricultural production and scientific experiments. Especially the marine remote sensing technology that flourished in the seventies opens up a broad road for the application of laser in oceanography and has a great impetus to the development of oceanography. The use of lasers in marine research, just as in other fields, has made great strides in the short term. Has successfully used laser underwater detection and communication. Remote sensing of marine physical elements on the surface and subsurface using airborne lasers; detection of ocean depths and mapping of shallow seabed topography. In addition, the use of laser fluorescence and Raman spectroscopy is being explored
