The 9.5 fs-long resulting pulses drive intrapulse difference-frequency generation (iDFG) in a 1 mm-thick LiGaS2 crystal and a specially designed waveplate is used prior to this crystal to further enhance the iDFG yield. This source paves the way for new experiments in 2D ultrafast ...
A Yb fiber laser pumped cw narrow-linewidth tunable mid-IR source based on a difference frequency generation (DFG) in a periodically poled LiNbO3 (PPLN) crystal for trace gas detection was demonstrated. A high power Yb fiber laser and a distributed feedback (DFB) laser diode were used as ...
Widely tunable mid-infrared generation via frequency conversion in semiconductor waveguides Phase matching in a multilayer AlGaAs waveguide is used to generate mid-IR (7.5-8.5 mu m) light through difference frequency generation (DFG) between a 155... DF Logan,M Giguere,A Villeneuve,... - 《Opt...
(PPLN) crystal to perform the difference-frequency generation for preparing the MIR pulsed illumination source. The signal beam passes through a spinning ground-glass diffuser before illuminating the object to smooth the speckles arising from the spatial coherence. Subsequently, the back-scattered ...
A new mid-infrared sensor platform is described, which combines difference frequency generation (DFG)-based tunable laser sources with simple direct absorption spectroscopy. DFG lasers operating in the 3–5micron window are tuned to access a variety of species in the C–H, N–O, and C–O str...
