Researchers Achieve Most Stable Laser Transmission Through 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.
Scientists from Australia have set a world record for the most stable transmission of a laser signal through the atmosphere. The team combined Aussie phase stabilisation technology with advanced self-guiding optical terminals to effectively eliminate atmospheric turbulence, an advance which could help test Einstein s theory of general relativity.
