Optical frequency combs technology has become a core technology in information systems over last decade. Recently, UCLA ...

“The turbulence in the air severely degrades images of objects in space, like our Sun, seen through our telescopes. But we can correct for that,” Dirk Schmidt, Adaptive Optics Scientist at the ...

The sun's corona—the outermost layer of its atmosphere, visible only during a total solar eclipse—has long intrigued ...

Abstract: We show here a laboratory demonstration of a free-space optical retrocommunication link using a laser at a wavelength of 1.064 μm. The link consists of a transmissive mechanically active ...

Abstract: Free-space optical (FSO) communication systems suffer from both average optical signal power loss and random power fading due to the atmospheric turbulence. For focused laser beams ...
