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 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.
