Researchers have demonstrated the smallest wavelength-tunable laser fabricated by microelectromechanical system (MEMS) technology. The laser features a wide tuning range which enables ...

In the past, a large variety of non-resonant nonlinear elements have been used within the NALM section to obtain the required nonlinear phase-shift for mode-locking operation. The novelty of our ...

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 ...

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 ...

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 ...

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 ...

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 ...

Short-pulse lasers are often used in time-resolved measurements with pulse lengths in the fs range. They are also used in material processing. The special properties of interaction between short ...

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 ...

The Ultrafast Optical Processing Group at INRS (Institut national de la recherche scientifique) has redefined the limitations and constraints for ultra-fast pulsed lasers. As reported in Nature ...
