Abstract :
A new mid-infrared tunable spectroscopic source based on fibre coupled difference frequency generation in bulk periodically-poled LiNbO 3 for trace gas detection is reported. The source mixes the outputs of a fibre coupled external cavity diode laser and a 1083 nm seeded Yb-doped fibre amplifier. Powers up to 0.8 μW are obtained in the 3.8-4.3 μm range
