NLIR Technology

Nlir's mid infrared spectrometer with an optical lens

All of our mid-infrared detection products are based on sum-frequency generation (or upconversion) spectroscopy. In this nonlinear optical process, two photons annihilate in the creation of a new photon with the same energy as the sum of the originals. When mid-infrared light enters NLIR detectors, it is brought together with a high-power 1064 nm laser inside a LiNbO3  crystal; one photon from each of these fields annihilates by interacting with bound electrons in the crystal to create a photon in the near-visible range. The new photon exits the crystal and can now be measured using Silicon-based devices. In the conversion process, all properties of the mid-infrared photon, except the wavelength, are conserved.

Demo Of 1 GHz Mid-Infrared Detector

Lasse and Søren, NLIR’s experienced optics-engineer duo, are showing a simple measurement of a nano-second pulse at 3.8 µm from a super-continuum source. The pulse has a peak power of only 0.5 µW, but the response of the detector is 3 kV/W, so the oscilloscope can easily measure the signal without further amplification.
