Crystals reduce energy leaks from unwanted optical transitions, say US Army researchers

A project funded by the US Army Research Office (ARO) has developed a method of fabricating 3D photonic crystals, which could eventually lead to lightweight, high-efficiency lasers with potential uses in directed-energy weapons (DEW) and a range of other military applications.  

Lasers require some type of medium to support ...
