  abstract = {<p>Here, an extrinsic Fabry-Pérot interferometer-based optical fiber sensor is introduced to assess its dynamic/static response according to the acoustic/gas pressure performance. This sensor utilizes nitrogen-doped molybdenum disulfide (N-MoS<sub>2</sub>) and pristine MoS<sub>2</sub>&nbsp;diaphragms. The N-MoS<sub>2</sub>&nbsp;nanosheets are synthesized using the pulse laser ablation in liquid nitrogen. According to empirical results, the N-MoS<sub>2</sub>&nbsp;diaphragm notably enhances the sensitivity of the sensor against the pristine one. Moreover, both diaphragms exhibit a linear relationship between sensor output and acoustic pressure, demonstrating a nearly flat acoustic frequency response ranging 8&nbsp;Hz-10&nbsp;kHz. Regarding the pressure measurements, the spectral sensitivity of the N-MoS<sub>2</sub>&nbsp;diaphragm is ∼16&nbsp;% larger than that of pristine. This sensor is capable of measuring the manometric pressures up to 250&nbsp;mbar with an accuracy of 0.001&nbsp;mbar.</p>
