Paper Abstract
We report on three different quartz enhanced photoacoustic (QEPAS) sensors operating in the near-IR, mid-IR and THz
spectral ranges, employing quartz tuning forks of different sizes and shapes. To test our sensors in the near-IR we used a
diode laser working at 2.7 μm, while in the mid-IR we employed a quantum cascade laser (QCL) operating at 7.9 μm,
fiber-coupled to the QEPAS cell. In the THz range we employed a QCL emitting at 2.95 THz. H2S absorption features
with line-strength up to 10-20 cm/mol were selected and QEPAS normalized noise-equivalent absorption in the 10-10
W•cm-1•Hz-1/2 range was achieved..
