Laser Focus World has recently published ”Fiber Lasers: Mid-IR laser source is widely tunable for standoff explosives detection”, an article showing the technical aspects and application behind our tunable Mid-IR laser.
Here is an excerpt from the article:
”…Genia Photonics has developed a mid-IR laser source based upon nonlinear difference frequency generation (DFG) of its commercially available picosecond synchronized laser (SL). DFG is a nonlinear process (see Fig. 1) in which two photons of different energies are mixed in a proper nonlinear material to produce a third photon with the energy corresponding to the difference in frequency of the two incident photons. By application of DFG to the rapid spectrally tunable picosecond pulses from the laser, it becomes possible to obtain a tunable mid-IR source with impressive spectral resolution (better than 3 cm-1).”
