When NASA's Lunar Laser Communication Demonstration (LLCD) begins operation aboard the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission managed by NASA's Ames Research Center in Moffett ...

Researchers have redefined the limitations and constraints for ultra-fast pulsed lasers. They have produced the first pulsed passively mode-locked nanosecond laser, with a record-low and ...

A new laser link with the International Space Station could do what optical fiber has done for internet access on Earth — by turning orbital communications from painfully slow dial-up to blazing-fast ...

In late 2023, NASA tested a new hybrid laser/radio antenna to downlink data from 20 million miles (32 million kilometers) away at a rate of 15.63 megabits per second – about 40 times faster than radio ...

Americans — no, make that humans — are a greedy bunch when it comes to Internet connectivity. We consume bandwidth at ever-increasing rates, which has led to capacity problems. The U.K. recently went ...

Scientists at the Stanford Linear Accelerator Center (SLAC) have devised a new way of creating twisted laser beams -- optical vortexes -- for carrying vast, near-infinite amounts of data down optical ...

Conventional lasers emit radiation at a single wavelength, so applications that require many wavelengths often need several lasers. Existing broadband lasers – which are usually based on ...

Concerns that the bandwidth of the light source for optical lithography can affect pattern quality are not new. No lens material is completely free from chromatic aberration: the refractive index ...

Researchers at TU Wien (Vienna, Austria) and ETH Zurich (Switzerland) have succeeded in generating ultrashort terahertz waves. With lengths of just a few picoseconds, these pulses are suited to ...

US Navy awards $7M contract for ITT Exelis and Novasol to build a line-of-sight system to handle escalating data needs. The US firms ITT Exelis and Novasol are to complete development of a ...
