redOrbit Staff & Wire Reports — Your Universe Online A team of Northwestern University researchers have developed a laser that they claim creates the purest, brightest, and most powerful beam ever developed for use in standoff sensing applications. Manijeh Razeghi, a Professor of Electrical Engineering and Computer Science in the university's McCormick School of Engineering and Applied Science, and colleagues have crafted a new resonator that they believe will produce improved...

New Generation Of Superlattice Cameras Add More 'Color' To Night Vision
2011-10-20 07:00:00

Recent breakthroughs have enabled scientists from the Northwestern University´s Center for Quantum Devices to build cameras that can see more than one optical waveband or “color” in the dark. The semiconducting material used in the cameras — called type-II superlattices — can be tuned to absorb a wide range of infrared wavelengths, and now, a number of distinct infrared bands at the same time. The idea of capturing light simultaneously at different wavelengths...

EVANSTON, Ill. --- New technology developed at Northwestern University has the potential for broad application in the detection of terrorist activities such as missile attacks on U.S. troops. Scientists at the Center for Quantum Devices (CQD) have demonstrated, for the first time, uncooled infrared imaging using type-II superlattice technology. This significant development could lead to smaller, faster and less expensive hand-held infrared imaging devices. High-speed infrared (IR) imagers...

EVANSTON, Ill. -- The difficulty of detecting the presence of explosives and chemical warfare agents (CWAs) is once again all too apparent in the news about the London bombings. In a significant breakthrough, researchers at Northwestern University's Center for Quantum Devices have demonstrated a specialized diode laser that holds promise as a weapon of defense in both civilian and military applications. Once optimized, the tiny laser could quickly detect explosives and CWAs early and warn...
