We report on recent developments of widely tunable, continuous-wave
(CW) laser sources based on difference-frequency generation (DFG)
in nonlinear optical materials. The state-of-the-art of CW DFG technology
will be reviewed. Applications of the DFG-based laser source to high-resolution
molecular spectroscopy and trace gas detection will be presented.
New development trends of DFG will be discussed
