概要
- 論文の詳細を見る
We report laser oscillations in whispering-gallery modes (WGMs) of a microsphere with its cavity quality factor Q unchanged for varied optical pumping intensities well above the laser threshold. Laser gain was present only in the evanescent-wave region of the lasing WGM around the microsphere equator, and thus pumping-induced Q degradation could be minimized, resulting in Q values maintained at 8(2) x 10^9 regardless of the pumping strength.
