Daylight Solutions, Inc. (Daylight Solutions) has introduced two new mid-IR tunable laser systems with wavelengths, 3.3um and 4.5um, to monitor environmental and industrial greenhouse gases. The 3.3um wavelength was developed in partnership with Jerry Meyer at the Naval Research Laboratory and 4.5um was developed with partners, AdTech and others. These two new wavelengths enable to detect methane, ethane, nitrous oxide, carbon monoxide, water, and other hydrocarbons.

Since long time, the utilization of spectroscopy to monitor different gases has been preferred by researchers for its accuracy and effectiveness. But the lack of portable easy to use laser systems with advanced capabilities in the spectral region of 3-5um have limited the use of this technique for greenhouse emissions.

By integrating two wavelengths into the company’s continuous wave, mode-hop-free (CW-MHF) laser system, researchers can now have access to high resolution spectroscopy sources.

The company’s laser systems are based on its external cavity, quantum cascade laser (ECqcL) technology. These systems enable true continuous wave, mode-hop-free tuning over 100 wavenumbers at wavelengths throughout the mid-infrared region.

“The addition of these new wavelengths provides advanced capabilities for atmospheric monitoring and combustion diagnostics research,” says Timothy Day, CEO/CTO of Daylight Solutions. “We are excited about the expansion of wavelength coverage down to 3.3 microns. This is just another example of our commitment to develop cutting edge tools for the environmental monitoring and research community.”
