BT could use laser pistols to shoot down drones used by eco-activists, terrorists or pranksters – The Sun.

With LASER guns, BT was able to shoot down drones after a million-pound contract was signed. The telecommunications giant can now also resort to specialized detection technicians. 3 BT has signed a multi-million pound agreement with DroneShield, which has worked with the British Army Prisons, stadiums and airports were among the customers who wanted to invest in technology. BT signed …

New laser vibration sensor detects buried objects from moving vehicles

The sensor is designed to improve detection of landmines and non-destructive testing. Detecting landmines can be a challenging and slow process. If captured by a moving vehicle, it would speed up the process, but at the expense of accuracy. At the Optical Society Laser Congress (OSA), held in Vienna, Austria from September 29 to October 3, 2019, researchers from the …

Europe launches second EDRS space laser satellite

Copyright ESA Caption The system will now consist of two celestial nodes – a third will follow before 2025 Europe has launched the second satellite in its space laser telecommunications network. It will use optical beams to retrieve images and data from other spacecraft and then bring this information to the ground. EDRS-C, as it is known, was launched on …

Laser trick produces high-energy terahertz pulses

A non-linear crystal generates energy from a terahertz pulse (right). Credit: DESY, Lucid Berlin              A team of scientists from DESY and the University of Hamburg has achieved an important milestone in the quest for a new type of compact particle accelerator. Using ultra-powerful pulses of laser light, they were particularly high-energy flashes of radiation in the terahertz range having …

Laser technology could allow the use of tough material for next-generation electronics

Graphene, a super tough wonder material, has not yet made it into electronics because it does not conduct any electrical current itself. The researchers used a laser technique to permanently clamp graphene into a structure that allows the flow of electrical current. Credit: Purdue University / Gary Cheng In 2004, the researchers discovered a super-thin material that is at least …

Researchers transmit data via a semiconductor laser, opening the door to ultra-high-speed Wi-Fi

This device uses a frequency comb laser to emit and modulate microwaves wirelessly. The laser uses different frequencies of light. The researchers use this phenomenon to send a song wirelessly to a receiver.

NASA's asteroid sample shot Bennu with a laser, and this is the result

NASA's OSIRIS-REx mission has been steadily progressing since the spacecraft arrived at the diamond-shaped space rock known as Bennu a few months ago. The rock ends up being far more , well, dirty than NASA originally expected. Bennu's surface is ready to be dropped on NASA's team that's ready to take a look at the asteroid to collect samples. Related …

NASA's asteroid probe fired Bennu with a laser, and that's the result

NASA's OSIRIS REx mission has been steadily advancing on the diamond-shaped space rock Bennu since the spacecraft arrived several months ago, but not everything went according to plan. The stone ended far more Well, dirtier than originally expected by NASA. Bennu's surface is full of debris, which poses a challenge for the NASA team to decide where the probe must …
