Capasso has expanded upon the Quantum Cascade Laser that debuted in 1994 by combining an array of multiple lasers emitting light of varying wavelengths in a tiny, more portable chip...
...That chip, the brainchild of applied physics professor Federico Capasso, has seemingly limitless applications—in areas ranging from medicine to intelligence gathering...
Applications of the laser chip may radiate into environmental sciences, as it will soon monitor the changing concentrations of greenhouse gas emissions, Capasso said. He, along with atmospheric chemistry professor James G. Anderson, plans to collaborate with NASA to send lasers into the stratosphere to study the effects of global warming...
Although quantum cascade lasers are already used to study carbon dioxide concentrations, the new chip with the allows researchers to monitor many different gases at the same time, said research associate Mikhail A. Belkin...
...small laser chip may also be used for intelligence gathering in satellites and planes by detecting whether factories are releasing toxic compounds through their smoke...
