A tunable high resolution cw difference frequency spectrometer applying the non-linear crystal AgGaS2 and two diode lasers as pump sources and experiments with this setup are presented. In contrast to the majority of known applications of the difference frequency mixing with solid state or gas lasers, we apply two single mode diode lasers with emission wavelengths of 690nm and 805nm, respectively...
The design and first experiments with atunable high-resolution cw difference-frequency spectrometer applying non-critical phasematching type I (90) in AgGaSe2 and two diode lasers as pump sources are presented. Asingle-mode FabryProt-type tunable diode laser (TDL) and an external-cavity diode laser (ECL) were combined to generate radiation in the mid-infrared region near 7.2m. With aTDL at awavelength...
