NLIR technology offers
Our products offer innovative optical sensing solutions that enable many industries and researchers to overcome their challenges in mid-infrared spectroscopy and accomplish the impossible.
NLIR Technology
All of our mid-infrared detection products are based on sum-frequency generation (or upconversion), which is a highly sophisticated nonlinear optical process where 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 one of our detectors, it is brought together with a high-power 1064 nm laser inside a LiNbO3 crystal; one photon from each of these fields annihilate 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.
