Abstract
Tunable mid-infrared radiation in the spectral range between 6.8 micrometer and 12.5 micrometer is generated via nonlinear optical difference-frequency-generation in AgGaS2. The input radiation that is needed for this process is provided by two high-power single mode diode-lasers. The combination of this MIR-laser source with a MIR-detector and lock-in detection technique has very interesting applications in spectroscopy. The on-line performance of this MIR-spectrometer is shown as single rotational lines of molecules are probed in the gas phase and in the vapor extracted from contaminated soil samples.
