摘要：
A new widely tunable source in the infrared for use in high-resolution spectroscopy and trace-gas detection is described. This spectroscopic source is based on Difference Frequency Generation (DFG) in gallium selenide (GaSe) and is continuously tunable in the 8.8-15.0 mu m wavelength region. Such a DFG source operates at room temperature which makes it a useful alternative to a lead-salt diode-laser-based detection system that requires cryogenic temperatures and numerous individual diode lasers.
