I saw another paper, where they calculate Q-factor for isolated peaks in a random laser. Below is a picture from a paper titled : Random Lasing with a High Quality Factor over the Whole Visible Range Based on Cascade Energy Transfer. They measure bandwidth of 0.05nm at FWHM.

Many papers about random lasers mention the Q-factor of random lasers. Since a random laser has multiple peaks close to each other like shown in the figure. Does each of these peaks correspond to a unique random lasing mode, or is it just a single mode? Similarly what is the right way to...
