“…Also, amplitude of the acoustic wave registered by the mechanical resonator is defined by optical radiation power that removes the requirement for measurement chamber length, which is important for Bouguer's law-based spectrometers [1]. These benefits make it attractive to use infrared (IR) PAS for express local control of pollution or greenhouse gases in the ground atmosphere [2]. Terahertz (THz) PAS also can be used for this goal.…”

Infrared laser photo-acoustic spectroscopy provides very high sensitivity of a gas sample analysis when high-power tunable laser radiation sources and resonant photo-acoustic detectors (PADs) are used. In the resonant PAD, the acoustic signal generated by absorbed laser radiation in a measurement chamber is amplified proportionally to a Q-factor of the acoustic resonator. But, compact tunable high-power lasers (with power above 100 mW) still are not widely spread in the terahertz spectral range. One of the ways to achieve an acceptable sensitivity of terahertz photo-acoustic spectroscopy is using PADs with a very high Q-factor. The latter can be achieved using PAD with a quartz tuning fork. The current state in this field is presented in the review.
