Abstract
The generation of tunable laser radiation in the specral range 5 to 10 μm is of general interest for the spectroscopy because most of the fundamental vibrational modes of molecules are within this spectral region,1 However, there is still a lack in simple, compact, portable, and rugged mid-infrared laser sources. In this context, diode-lasers and difference-frequency generation (DFG) in new nonlinear media, such as AgGaS2, have drawn considerable interest in the construction of compact cw laser spectrometers.2-3
