Abstract: 

The invention of the laser has greatly advanced modern science and technology, and recently, microscale lasers have emerged as a cornerstone of modern information technology. In this talk we review the background, underlying physics, and development of laser miniaturization while also discussing the intriguing light-matter interaction and diverse applications of lasers at the nanoscale.
