Air monitoring by spectroscopic techniques
TL;DR: Sigrist et al. as mentioned in this paper proposed the use of a Tunable Diode Laser Absorption Spectroscopy for Atmospheric Measurements (H. Schiff, et al.).
Journal ArticleDOI
Laser generation of acoustic waves in liquids and gases
TL;DR: In this article, the effects of photoacoustic spectroscopy (PAS) in gaseous media are reviewed and a simple experimental method for the determination of Beyer's nonlinearity parameter B/A is presented.
Journal ArticleDOI
Laser‐generated stress waves in liquids
TL;DR: In this article, a new spherical model is proposed, where the transient heating caused by the laser impact, represented by the three-dimensional heat pole, corresponds to a Gaussian distribution of the excessive temperature in space, and thus to the TEM00 mode of the incident laser beam.
Journal ArticleDOI
Trace gas monitoring with infrared laser-based detection schemes
TL;DR: In this article, the success of laser-based trace gas sensing techniques crucially depends on the availability and performance of tunable laser sources combined with appropriate detection schemes, which are based on sensitive absorption measurements and comprise direct absorption in multi-pass cells as well as photoacoustic and cavity ringdown techniques.
Journal ArticleDOI
Trace gas monitoring by laser photoacoustic spectroscopy and related techniques (plenary)
TL;DR: In this article, the performance of various spectroscopic systems with different lasers (gas lasers, nonlinear optical sources like optical parametric oscillators and difference frequency generation, near-infrared external cavity diode lasers, quantum cascade lasers) and different detection schemes (photoacoustic, multipass transmission, cavity ringdown) are discussed and illustrated with examples from various areas.
