Modes and Q-factor(s) of a random laser

[QUOTE="samchan, post: 6190933, member: 663087"] 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? [ATTACH type="full" width="358px" alt="244799"]244799[/ATTACH] Similarly what is the right way to calculate the Q-factor of this random laser (example plot shown below) : Should it be wavelength at Peak1 divided by FWHM at (blue line) or wavelength of Peak1 divided by FWHM at (red line) ? [ATTACH type="full" width="305px" alt="244800"]244800[/ATTACH] Should the Q-factor be calculated at -3db or FWHM? [/QUOTE]
