Organic laser diodes move from dream to reality

Researchers from Japan have demonstrated that a long-elusive kind of laser diode based on organic semiconductors is indeed possible, paving the way for the further expansion of lasers in applications such as biosensing, displays, ...

Scientists build the smallest optical frequency comb to-date

Optical frequency combs are laser sources whose spectrum consists of a series of discrete, equally spaced frequency lines that can be used for precise measurements. In the last two decades, they have become a major tool for ...

Laser diode detects counterfeit olive oil

Researchers at the Complutense University of Madrid (UCM) and the Scintillon Institute in the U.S. have designed a sensor that can detect counterfeit olive oil labeled as extra virgin or protected designation of origin.

Directivity to improve optical devices

A team of researchers from the Dutch institute AMOLF, Western University (Canada), and the University of Texas (United States of America) recently demonstrated the use of algorithmic design to create a new type of nanophotonic ...

Using diamonds to recharge civilian drones in flight

A small lab-grown diamond measuring a few millimeters per side could one day enable civilian drones to be recharged in mid-flight through a laser. Thanks to the diamond, the laser beam can remain strong enough over a long ...

Frequency-stable laser systems for space

JOKARUS experiment on sounding rocket successfully completed. Corner stone for laser ranging measurements with the highest precision and precursor for optical satellite navigation systems.

A curious quirk brings organic diode lasers one step closer

Since their invention in 1962, semiconductor diode lasers have revolutionized communications and made possible information storage and retrieval in CDs, DVDs and Blu-ray devices. These diode lasers use inorganic semiconductors ...

Research team develops record laser on chip

Working in collaboration with the Lionix company, researchers from the University of Twente's MESA+ research institute have developed the world's most narrowband diode laser on a chip. This laser represents a breakthrough ...

New technology could revolutionize 3-D printing

A technology originally developed to smooth out and pattern high-powered laser beams for the National Ignition Facility (NIF) can be used to 3-D print metal objects faster than ever before, according to a new study by Lawrence ...
