Transition metal dichalcogenides have captured the interest of the scientific community over the past decade, given their intriguing light-matter interactions in van der Waals membranes, toward a wide variety of platforms. In this regard, NbSe2 shows emergent behaviour, such as charge density waves and superconductivity upon cooling down to cryogenic liquid helium temperatures. Here we report on the use of a superconducting NbSe2 absorber layer for transducing incoming optical radiation into a thermally-driven resistive readout, motivated by the large body of work on traditional transition-edge sensors (TES) in classical bulk superconductors. Through our empirical studies, multilayer NbSe2 crystals were electrically probed, which allowed us to make prototypical demonstrations of the transduction mechanism from the superconducting state to the normal state upon irradiation with several optical sources. Our preliminary studies open up possibilities for exploring NbSe2 in superconducting TES bolometers as radiation detectors.
