The Chemical Analysis by Laser Interrogation of Proliferation Effluents (CALIOPE) Program is conducting research in the applicability of laser remote sensing systems to the nuclear nonproliferation problem. The goal is to develop and demonstrate laser-based systems for remote optical detection and characterization of chemical effluents from nuclear proliferation activities, beginning with laboratory and field experiment evaluation, and progressing, where feasible, to proof-of-concept demonstrations.
Laser remote sensing is currently used in a number of climatology and pollution control applications, such as measuring water vapor in the atmosphere and emissions from a chemical plant. The difficulty in applying laser remote sensing to nonproliferation is the extreme long range involved and the necessity to have a system sensitive to a wide suite of chemical effluents. This program is studying the physical phenomena and technical limitations in state- of-the-art laser sensing systems, with the goal of advancing techniques and hardware to a point where laser remote sensing systems can detect and measure airborne pollutants from a significant distance. Specific techniques under study are differential absorption light detection and ranging (infrared and ultraviolet), ultraviolet fluorescence, and enhanced Raman scattering. Advanced, tunable lasers needed to implement these techniques are also under development. This program supports the DOE mission to provide technology to detect the proliferation of nuclear weapons, and is part of the Nonproliferation and Verification Research and Development program.
