    "abstract": "We have demonstrated an ultrahigh-Q whispering-gallery-mode (WGM) microsphere\nlaser based on the evanescent-wave-coupled gain. Dye molecules outside the\nsphere near the equator were excited, resulting in WGM lasing in the lowest\nradial mode order. The loaded quality factor of the lasing WGM was 8(2)\\times\n10^9, the highest ever achieved in the microlaser.",
