Tiny Lasers Could Help Fight Bio-Weapons
WASHINGTON, March 7, 2014 — Biochemical weapons could be a big threat, but a new DARPA program is proposing a very small solution: tiny lasers.
The research agency has established a program called Laser UV Sources for Tactical Efficient Raman, or LUSTER, which will begin developing a small-scale, portable and budget-conscious Raman spectroscopy system that relies on efficient, high-power, tiny UV lasers. UV happens to be the optimal wavelength for Raman-based standoff detection.
Such detection and...
