WebApr 9, 2024 · We report photoacoustic Brillouin spectroscopy of gas-filled anti-resonant hollow-core fibers (AR-HCFs). Pump absorption of gas molecules in a gas-filled AR-HCF excites the acoustic resonances of the fiber, which modulates the phase of a probe beam propagating in the fiber. WebNov 23, 2024 · For example, the photoacoustic light source 105 may be coupled to other components of the system 100 via a multi-mode optical fiber. In another example, the Brillouin light source 110A and/or the light sensor 110B may each be coupled to other components of the system via single mode optical fibers, e.g., polarization maintaining …
