Abstract

A swept-wavelength external cavity quanhim cascade laser measures broadband infrared absolution spectra from 2050-2300 cm-1 at a 100 Hz rate to determine time-resolved temperabrre and column densities of CO, CO2, H2O, and N2O in high-explosive detonations.

Abstract

We characterize performance of a standoff detection system based on a swept-wavelength external cavity quantum cascade laser (ECQCL) tuned from 955-1195 cm-1 (8.37-10.47 pm) at 400 Hz for detection of transient chemical plumes.
