Abstract

We experimentally demonstrate and test a new type of laser where emission is mediated by water waves. Our device is similar to Brillouin lasers, but exploits water-waves (instead of acoustical waves). In our study, we fabricate resonators that co-host capillary and optical modes, control them to operate at their non resolved sideband regime, and observe stimulated capillary scattering and coherent excitation of capillary resonances at kHz rates. In more details, we experimentally measure optical quality factor near million, capillary quality factor near 20 and lasing threshold at 70 microwatt. Knee shaped power dependance, that is typical to lasers, is measured together with line narrowing as power increases. By exchanging energy between electromagnetic and capillary waves, we bridge interfacial-tension phenomena at the liquid phase boundary to optics, and might impact optofluidics by allowing optical control, interrogation and cooling of water waves.
