Optoacoustic imaging powered by short bursts of continuous wave (CW) lasers can stimulate the emission of ultrasound waves inside an animal or in human subjects. The method can noninvasively capture blood flow and produce ...
A terahertz laser designed by MIT researchers is the first to reach three key performance goals at once—high constant power, tight beam pattern, and broad electric frequency tuning—and could thus be valuable for a wide ...
