UW team refrigerates liquids laser
2015/12/7
Since the first laser was invented in 1960, they’ve almost always given off heat — either as a useful tool, a byproduct or a fictional way to vanquish intergalactic enemies.But those concentrated beam...
REAL-TIME VIDEO-BASED RECONSTRUCTION OF URBAN ENVIRONMENTS
