德国一所大学的研究人员研制成功一种用特殊光纤作导体的微型半导体激光器 ,利用它可以制成高清晰度的袖珍激光彩色电视机。该激光器只需电池就能产生很高的功率 ,且不需要附加任何冷却装置。此外 ,这种激光器的体积可微型化到一只烟卷大小 ,非常适合作为激光电视机光源 ,从而 Researchers at a German university have succeeded in developing a miniature semiconductor laser with a special optical fiber as a conductor, making it possible to create a high-definition pocket-sized laser color television set. The laser can produce very high power with only the battery, and does not need to add any cooling device. In addition, the size of this laser can be miniaturized to the size of a cigarette and is ideally suited as a laser TV light source for
