WGM lasing is clearly evidenced by the sharp peaks in the spectrum. score 308 The measured lasing spectrum is in agreement with the first-order TE modes from 251 to 257 (Fig 2 e and theoretical calculation of the mode number of in the Supporting Information) The optical design of WGM sensors is based on use of sufficiently high-quality resonators
