Photoacoustic Hydrocarbon Spectroscopy Using a Mach-Zehnder Modulated cw OPO
This paper describes a new photoacoustic spectrometer for the investigation of hydrocarbons based on a continuous wave optical-parametric oscillator (OPO). Two modulation methods for the generation of the photoacoustic signal are compared. In addition to the traditional modulation by a mechanical ch...
