a Schematic representation of the optical set-up (for details please see Methods section). b Typical lasing spectra of a DG microsphere in 50 µM R6G under varied pumping energy from 60.3nJ to 1262nJ. c Lasing thresholds of DG (green) and R6G (pink) are at 209nJ and 309nJ, respectively. d, e Lasing frequencies of DG (green) and R6G (pink) are independent of pumping duration (d) and number of pulses (e).
