Pulsed quantum cascade laser based hypertemporal real-time headspace measurements

Boyson, Toby K.; Rittman, Dylan R.; Spence, Thomas; Calzada, Maria; Kallapur, Abhijit G; Petersen, Ian; Kirkbride, Kenneth; Moore, David S.; Harb, Charles


Optical cavity enhancement is a highly desirable process to make sensitive direct-absorption spectroscopic measurements of unknown substances, such as explosive, illicit materials, or other species of interest. This paper reports advancements in the development of real-time cavity ringdown spectroscopy over a wide-bandwidth, with the aim to make heaadspace measurements of molecules at trace levels. We report results of two pulsed quantum cascade systems operating between (1200 to 1320) cm -1 ...[Show more]
