title = "Stimulated Raman photothermal spectroscopy on an optical nanofiber for hydrogen detection",
abstract = "We report stimulated Raman photothermal spectroscopy (SRPTS) on an optical nanofiber (NF) for tracing hydrogen. With an NF of \textasciitilde{}50 mm in length and \textasciitilde{}700 nm in diameter, we have demonstrated hydrogen detection down to 274 ppm under 1 bar with 350 mW pump and 150 mW Stokes power and 1 s lock-in time constant.",
