ams Osram just announced a big leap in laser tech for autonomous vehicles—a five-junction edge-emitting laser that could seriously boost lidar […]

Chinese researchers have successfully charged a drone using just a laser, in a breakthrough that could change how we approach unmanned flight

NASA is partnering with SpaceX to outfit the Artemis III Orion spacecraft with Starlink laser communications terminals to assist with high-definition video transmissions and data-heavy mission downlinks.

Hi, is it possible to solve the neon bleeding issue with lasers, if continuously pumped more neon in, or if you used a material which wasn't glass?

China’s satellite laser downlink shows how a low-power beam from extreme distance could change the race for faster, more resilient space communications.

A laser reshapes paper at the molecular level, creating bonds strong enough to hold 20 kg—without a drop of glue.

A new laser-powered wireless system uses light to deliver data at speeds exceeding 360 Gbps. It could enable faster, more efficient indoor networks while reducing interference and energy use. Modern life runs on fast, reliable wireless connections. Video calls, streaming, virtual reality, and connected devices all depend on networks that already support billions of users. [...]

For decades, satellites have been beaming data from Earth to space and back via radio waves. But with the growing number of spacecraft in orbit and the increasing quantities of data beaming back to Earth, radio spectrum is hitting its physical limits. For about a decade, companies and research institutions have been working on higher-bandwidth, optical technologies that would remove current data …

The Royal Navy prepares to field a game-changing laser weapon against drones and missiles.

France is developing advanced space weapons capable of targeting satellites using laser technology, hinting at a major shift in how future wars might unfold far above Earth.

They can sometimes identify not only the types, but also how many there are. One day, lasers might be able to keep track of what germs are around us.

From communication and entertainment to manufacturing and health care, lasers have revolutionized the way we interact with the world around us. They have become an integral part of our modern existence, pushing the boundaries of innovation as indispensable components of countless devices and industries. Lasers produce narrow beams of light. When the laser's light interacts with the surface of a m…

A new algorithm has been developed for simulating the amplification of femtosecond pulses in fiber amplifiers, for example. It allows one to properly describe both the time dependence due to gain saturation and the frequency dependencies of optical fields and gain. The details have been published in the open-access journal Optics Express.
