Researchers at the VTT Technical Research Centre of Finland have developed optical interruption of a mid-infrared quantum cascade laser, which could cut costs of a sensitive type of spectroscopy
Researchers from VTT Technical Research Centre of Finland have developed optical interruption of a midinfrared (MIR) quantum cascade laser (QCL) using a near-infrared (NIR) laser diode for cavity ring-down spectroscopy (CRDS).
A new frequency modulated continuous wave (FMCW) lidar technique is being used to test the thickness and length of optics
Researchers have developed a new method to better model human stroke which uses artery-targeted photothrombosis. This shows a clear improvement on traditional methods by creating a larger penumbra for a longer amount of time while maintaining the practical results of the traditional model.
Microchips are extremely useful when studying sample sizes less than a milliliter in volume. Researchers from Massachusetts Institute of Technology and Georgia Institute of Technology both used microchips in conjunction with infrared diode lasers to conduct experiments on small-scale environments. The absorption spectrum of water dictated the wavelength choices made by the researchers. On one hand, negligible heating of the water (via absorption) was desired, so the wavelength was chosen away from an absorption peak of water.
