Abstract
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 s elenide (GaSe) and is continuously tunable in the 8.8-15.0 mu m wavele ngth region. Such a DFG source operates at room temperature which make s it a useful alternative to a lead-salt diode-laser-based detection s ystem that requires cryogenic temperatures and numerous individual dio de lasers.
