Why the Navy’s next laser fight is really about cooling and ship power
It needs space, weight, power and cooling which can be a challenge on our current surface combatants. The engineering center ...
Accurate high magnification of small aperture laser beams has traditionally been a challenge because the optics associated with such a beam expander are difficult to test using an optical ...
