Quantum Cascade Lasers

Machine olfaction for Industry 4.0

Bespoke quantum cascade lasers for instant parts-per-billion analysis of airborne substances


How it works

  • Idea & Inception

    Initial understanding of your requirements to establish a potential fit between you and us. The deliverables from these early discussions are an improved understanding of your needs and solutions available from Stratium®

  • Planning

    We will work with you to fully understand your target specification and business needs. We'll develop a project schedule, resulting in a target unit price and lead-time for a laser designed to meet your exact requirements.

  • Development

    Using state-of-the-art molecular beam epitaxy (MBE) and device fabrication tools, we will develop your quantum cascade laser design. There will be extensive product testing and QA throughout this phase.

  • Deployment & Launch

    Each laser supplied will have burn-in, to ensure stable and robust operation in your system. We will provide you with laser test, characterisation and lifetime data for acceptance and launch of your system.

  • Support & Optimisation

    We will provide you with ongoing support for the lifetime of the product and update you on new evolutionary versions that deliver continuously improved mid-infrared emission for your application.


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.
— 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.
— Sarah A Fulton, Director of Research and Innovation Services, University of Sheffield
