Quantum Cascade Laser-Based Photoacoustic Sensor for Trace Detection of Formaldehyde Gas
We report on the development of a photoacoustic sensor for the detection of formaldehyde (CH(2)O) using a thermoelectrically cooled distributed-feedback quantum cascade laser operating in pulsed mode at 5.6 μm. A resonant photoacoustic cell, equipped with four electret microphones, is excited in its...
