[[Dye laser]]s use an organic dye as the gain medium. The wide gain spectrum of available dyes, or mixtures of dyes, allows these lasers to be highly tunable, or to produce very short-duration pulses ([[on the order of]] a few [[femtosecond]]s). Although these [[tunable laser]]s are mainly known in their liquid form, researchers have also demonstrated narrow-linewidth tunable emission in dispersive oscillator configurations incorporating solid-state dye gain media. In their most prevalent form, these [[solid-state dye lasers]] use dye-doped polymers as laser media.

[[Bubble laser]]s are dye lasers that use a [[Bubble (physics)|bubble]] as the optical resonator. [[Whispering gallery mode]]s in the bubble produce an output spectrum composed of hundreds of evenly spaced peaks: a [[frequency comb]]. The spacing of the whispering gallery modes is directly related to the bubble circumference, allowing bubble lasers to be used as highly sensitive pressure sensors.<ref name="miller">{{cite journal |last1=Miller |first1=Johanna |title=Bubble lasers can be sturdy and sensitive |journal=Physics Today |date=2024 |volume=77 |issue=3 |pages=12–14 |publisher=American Institute of Physics |doi=10.1063/pt.xafv.lnix |doi-access=free |bibcode=2024PhT....77c..12M }}</ref>
