很难找到一本科幻作品其中完全不提及激光。书中常把激光用作致命武器、医疗器械，有时还用激光捕捉敌方飞船或使飞船偏离航向。作为物理学家，当然很难相信用激光捕捉宏观物体，但若快速测览一下最近的有关研究，就会发现情况十分不同。在生物技术实验室中，激光现已广泛用于? Difficult to find a science fiction work which does not mention the laser. The book often use the laser as a lethal weapon, medical equipment, sometimes with laser capture enemy spacecraft or spacecraft departure from the course. As a physicist, of course, it is hard to believe that macroscopic objects are captured by lasers, but if you quickly take a quick look at the relevant studies, you will find that the situation is very different. In biotechnology laboratories, lasers are now widely used?
