RPMC and our partners collaborated with combustion researchers who were grappling with the inability of conventional sensors to deliver reliable, real-time data in the extreme heat, pressure, and chemical chaos of flame environments – a classic pain point where interference overwhelms signal and response lags hinder dynamic control. By supplying a robust quantum cascade laser platform tailored for harsh conditions, RPMC enabled the team to push beyond these barriers without compromising sensitivity or stability.

Laser Solution: Fiber-coupled mid-IR quantum cascade laser, tunable with narrow linewidth, used for sensitive absorption spectroscopy.

Outcome: Ensured stable, real-time radical monitoring under harsh conditions, driving progress toward more efficient and lower-emission combustion systems.
