Scientists shoot record-breaking laser into space in the hope of unlocking the secrets of time

Scientists shoot record-breaking laser into space in the hope of unlocking the secrets of time Adam Smith © Provided by The Independent The world record for the most stable transmission of a laser signal through the atmosphere has been broken.   Scientists from the International Centre for Radio Astronomy Research (ICRAR) and The University of Western Australia (UWA) broke the record using ‘phase stabilisation’ technology alongside advanced self-guiding optical terminals. We can correct for atmospheric turbulence in 3D, that is, left-right, up-down and, critically, along the line of flight, Benjamin Dix-Matthews, a PhD student at ICRAR and UWA, said. It allows us to send highly-stable laser signals through the atmosphere while retaining the quality of the original signal, Matthews continued, adding that its as if the moving atmosphere has been removed and doesn t exist.”

Laser Transmission Through Atmosphere

Researchers Achieve Most Stable Laser Transmission Through Atmosphere Written by AZoOpticsJan 25 2021 Researchers from the International Centre for Radio Astronomy Research (ICRAR) and The University of Western Australia (UWA) have achieved a new world record for the most stable laser signal transmission through the atmosphere.

Scientists have set a world record for the most stable transmission of a laser signal through the atmosphere, effectively eliminating atmospheric turbulence. While twinkling stars and shimmering mirages over hot roads are fascinating sights, many scientists would find research a whole lot easier if these phenomena didn’t exist. The atmosphere is composed of pockets of air of varying temperatures, which distorts the path of any optical signal that passes through. But these twists and turns of light make it difficult for astronomers attempting to accurately study the cosmos, or engineers communicating with satellites.
