摘要

2016 年，日本政府公布了一项关于建立新型社会的计划。该计划解释说，人类文明从狩猎采集开始，经历了农业和工业阶段，正迅速接近信息时代的终点。正如当时的首相安倍晋三所说："我们现在正在见证第五章的开启。- 这一章被称为 "社会 5.0"，将出现按需生产的商品、机器人看护、出租车和拖拉机。许多创新技术，如人工智能，可能是显而易见的。但有一项关键技术很容易被忽视：激光。

The Brightest Semiconductor Laser Ever: Photonic Crystals Enable Tiny Lasers to Melt Steel

IN 2016, THE JAPANESE GOVERNMENT ANNOUNCED a plan for the emergence of a new kind of society. Human civilization, the proposal explained, had begun with hunter-gatherers, passed through the agrarian and industrial stages, and was fast approaching the end of the information age. As then Prime Minister Shinzo Abe put it, “We are now witnessing the opening of the fifth chapter.” • This chapter, called Society 5.0, would see made-on-demand goods and robot caretakers, taxis, and tractors. Many of the innovations that will enable it, like artificial intelligence, might be obvious. But there is one key technology that is easy to overlook: lasers.
