利用高度聚焦的高光度光束作为热源的原理在历史上和文献中已有详细的记载并在日常生活中反复得到了证实。据说,阿基米德于公元前212年在锡拉丘兹战役中就曾利用聚焦的太阳光打垮了罗马舰队,这种威力已由无数的孩子们利用干树叶和碎纸片在小实验中得到了证实。在科学幻想文学作品中也大量刊载过关于利用高光度光束来熔化金属的装置以及在光路中汽化各种物体的装置。
The principle of using a highly focused, high-intensity light beam as a heat source has been documented in history and in the literature and has been repeatedly demonstrated in daily life. It is said that Archimedes in the battle of Syracuse in 212 BC had used the focus of sunlight to defeat the Roman fleet, the power of countless children have been using dry leaves and shredded paper in small experiments Confirmed. In sci-fi literary works, there have also been a large number of devices for melting metals using high-intensity light beams and devices for vaporizing various objects in the optical path.
