The laser, which has comparable output to a simple presentation pointer, potentially has the sensitivity and selectivity to canvas large areas and detect improvised explosive devices – weapons that account for around 60 percent of coalition soldiers’ deaths. Marcos Dantus, chemistry professor and founder of BioPhotonic Solutions, led the team and has published the results in the current issue of Applied Physics Letters. The detection of IEDs in the field is extremely important and challenging because the environment introduces a large number of chemical compounds that mask the select few molecules that one is trying to detect, Dantus said. “Having molecular structure sensitivity is critical for identifying explosives and avoiding unnecessary evacuation of buildings and closing roads due to false alarms,” he said Since IEDs can be found in populated areas, the methods to detect these weapons must be nondestructive. They also must be able to distinguish explosives from vast arrays of similar compounds that can be found in urban environments. Dantus’ latest laser can make these distinctions even for quantities as small as a fraction of a billionth of a gram.

Well I thought this is good news seeing how improvised explosive devices – weapons account for around 60 percent of coalition soldiers’ deaths.
This technology could really save lives and at the same time cause the Taliban to change their tactics and maybe come out and fight like real men.
If it works...
