Final Report Summary - ANSWER (Artificial nanomaterials for short wavelength emission in the infrared)
QCLs constitute the proper choice for achieving short wavelength emission as they turn out to be small, compact as well as robust. Compact, sensitive and rapid detection systems could be envisaged with proper laser sources which systems would apply for detection of hazardous substances and explosives in homeland security in airports, metro systems as well as points of mass transit or gathering.
