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).
Dutch start-up MantiSpectra has received investment from PhotonDelta and Innovation Industries, while Senorics is set to receive more than €2 million from the Development Bank of Saxony
High progress in optoelectronics technology, especially designed for infrared wavelength region (IR), is observed. The use of various spectroscopic methods allows to obtain detailed information on the chemical analysis of the leaking gas. Each of the spectroscopy methods is dedicated to different types of concentration measurements. We encourage you to read the article that explains and presents laser gas leak detection with infrared.
In this application note, Edinburgh Instruments utilises a Transient Absorption Spectrometer featuring dual detector options for direct kinetic and spectral measurements to Study a Molecular Triad’s Photoinduced Electron Transfer Reactions.
This paper explains how to use the MID-IR linear detector array in the sorting area. High performance optical sorting systems are the main application of multielement detectors. Optical sorting can be used in the mining, food, chemical and pharmacological industries.
The laser operates in fundamental mode with beam quality M2 < 1.05 for both beams. The beam shape is recorded at the output of the oscillator (magnified image of the output coupler) on a WinCamD-LCM-NE 1” beam profiler at the nominal operation point of the laser with 3.7 A pump current, approx. 7.8 W total pump power and 440 mW average output power from each comb.
The new development paves the way for portable dual-comb light sources for applications such as spectroscopy and precision distance measurement
Due to climate change, population growth and many other factors, farms will need to adapt to ever-worsening conditions. Spectroscopy plays a key role in developing the future of these farms.
A modular spectroscopy setup based on an Ocean Insight HR series high resolution spectrometer was used to monitor changes in argon plasma emission following the introduction of different gases to a plasma chamber. The measurements demonstrated the viability of modular spectroscopy components to acquire plasma emission spectra in real time from a plasma chamber. Plasma characteristics determined from these emission spectra can be used for monitoring and controlling plasmabased processes.
