Next Generation Gas Analysis

Powerful quantum cascade lasers to detect and quantify airborne substances


How it works


Stratium® designs and manufactures commercial-grade quantum cascade lasers from 3µm to 12µm, for demanding OEM applications


Using state-of-the-art lithography and device manufacturing tools, we are able to respond to bespoke requests to meet your exact requirements


We provide packaged devices for prototyping, process optimisation, product qualification and transfer to volume manufacture


What makes us different?

Stratium's quantum cascade lasers have been designed to deliver precise mid-infrared emission required for next generation gas analysers. Our proprietary Agura™ wavelength selection technology (Pat. Pend.) results in a compact, wavelength stabilised, low-noise and narrow-linewidth mid-infrared semiconductor laser source, suitable for the sensitive detection of molecular species using techniques such as cavity ring-down spectroscopy (CRDS), cavity enhanced absorption spectrometry (CEAS) and photoacoustic spectroscopy (PAS).


We're backed by Active Investors...

Development Bank of Wales (DBW) is pleased to co-invest with IP Group to back Stratium as its launches its Agura™ wavelength selection technology. Our investment will enable Stratium to undertake further research and development, scale up its technology and target new markets.
— Carl Griffiths, Technology Seed Fund Manager, Development Bank of Wales
It is fantastic to see innovation and research, which started here at the University, leading to the launch of a product capable of having such a positive impact in a number of industries.
