07 Aug Chromacity lasers used to monitor agricultural greenhouse gas and pollution emissions
Mid infra-red lasers used at the heart of FTIR spectrometer for wide area real-time gas analysis
Wednesday 7th August, Edinburgh, UK. CHROMACITY LTD., a world leader in development of infra-red lasers, Scotland’s Rural College (SRUC) and the UK Centre for Ecology and Hydrology (UKCEH) supported by Innovate UK will work together to develop and test new instrument technology for real-time in-the-field measurement of common greenhouse gases (CHGs) and atmospheric pollutants such as methane, carbon dioxide, nitrous oxide and ammonia.
The aim is to provide a step change in capability, addressing limitations of current measurement solutions, developing techniques for measuring source emissions in agriculture, agroforestry, forestry, landfill sites, anaerobic digestion plants, and wastewater treatment plants.
The proposed new Fourier-transform infra-red instrument works by analysing absorption of infra-red light over the light source to reflector path. Absorption is dependent on the concentration of gas under analysis, allowing gas concentrations in the path to be measured. This technique is proven but limited by the type of infra-red radiation source used for the analysis.
CHROMACITY’s key advancement derives from the use of its patented state-of-the-art broad bandwidth, tuneable infra-red pulsed single mode laser source. This advanced laser technology has a high quality, high brightness beam, which enables the system to cover an extremely wide measurement area, scanning a wide range of wavelengths that are absorbed by the main gases of interest.
The system will be capable of simultaneous stand-off detection of multiple pollutant gases, in real-time, and across a wide variety of agricultural settings. Using CHROMACITY’s patented optical parametric oscillator (OPO) technology, this demonstrator will be a showcase for greenhouse gas and pollution detection technologies.

About CHROMACITY
CHROMACITY is a world leader in the design, development, and manufacturing of advanced ultrafast pulsed fibre lasers. Based in Edinburgh, UK, the company specialises in fixed wavelength femtosecond and picosecond optical parametric oscillator (OPO) based tuneable laser systems. Based on a novel patented laser architecture that delivers ultra stable long-term performance, the fixed wavelength femtosecond fibre lasers work at 1040nm and 920nm, and the tuneable picosecond OPO lasers work across the near infra-red and mid infra-red wavelengths from 1.4um to 12um.
The lasers are used principally for scientific and industrial research including spectroscopy (materials analysis), microscopy (biological imaging), defect detection, pollution monitoring and broad variety of quantum applications.
All Chromacity’s lasers are compact, air-cooled devices, and offer unrivalled long term pulse stability without the need for on-going maintenance. The company sells its products either directly, or via a global network of distributors and agents.
