Thorlabs qepas acoustic detection module adm
(a) Schematic of dielectric-coated SPF <t>EW-QEPAS</t> setup for methane measurements in a gas box. The Acoustic Detection Module <t>(ADM)</t> is comprised of the QTF, mR tubes, and pre-amplifier. (b) Schematic of the side-polished fiber passing through the mR tubes and prongs of the QTF, showing the generated acoustic wave and the standing waves generated in the tubes. The length of the polished section is 17 mm. SMF: Single-mode fiber, QTF: Quartz Tuning Fork, mR: millimeter Resonator tube. (c) An image of the coated SPF passed through the resonator tubes and QTF prongs, held in position by the fiber rotators on either side with the visible camera to monitor the fiber position inside the gas box while pumping.

Article Snippet: In this study, a commercial QEPAS acoustic detection module (ADM) was used (Thorlabs ADM01).

Techniques: Generated

Comparison of 2 f QEPAS signals of 1% methane (by volume) in N 2 at 1653.7 nm obtained with an uncoated side-polished fiber and with ZrO 2 coated side-polished fibers of thicknesses 130, 153, 164, 170, 179, 192, and 196 nm. The increase in signal due to the zirconium oxide coating is calculated to be 153 times the uncoated fibers’ QEPAS signal.

Techniques: Comparison

(a) Solid black squares: Maximum 2 f QEPAS signal measured for 1% methane (by volume) in N 2 for different ZrO 2 coatings on the side polished fiber at 800 mbar. (b) Solid dots: Maximum 2 f QEPAS signal as a function of methane mixing ratio (100–500 ppmv) for the ZrO 2 coated SPF of thickness 179 nm. Red solid line: Linear regression applied to the QEPAS signal data. Data was collected using a digital lock-in amplifier with a time constant of 100 ms, a positive ramp with a period of 100 s covering 8.75 mA, and a modulation frequency of 6220.95 Hz with a depth of 5.1 mA.

Techniques:

Allan Deviation of the QEPAS signal as a function of the lock-in integration time for laser on-on peak (black) and laser off peak (red) in 500 ppmv of methane, and laser on-on peak in pure N 2 (green). The noise level decreased with increasing integration time following a trend of 1/ τ (blue).
