哈佛大学研究人员在直径仅为几百纳米的纳米线中,首次产生了激光输出。纳米线材料和制备技术的全球性进展,使科学家能够从放大自发辐射(ASE)到阈值以上的激光振荡的转变过程中观察纳米线中的激光输出。 Researchers at Harvard University have produced laser output for the first time in nanowires of just a few hundred nanometers in diameter. The global advance in nanowire materials and fabrication techniques allows scientists to observe laser output in nanowires from a process of amplifying spontaneous emission (ASE) to laser oscillation above threshold.
