In a study published in the journal
Nature Communications, the team behind the world record describe how they combined phase stabilization technology with advanced self-guiding optical terminals.
The researchers say their laser will allow science such as Einstein s theory of general relativity to be tested more precisely than ever before.
Record-breaking laser link
The combination of phase stabilization technology and advanced self-guiding optical terminals allows laser signals to be sent from one point to another without interference from the atmosphere. We can correct for atmospheric turbulence in 3D, that is, left-right, up-down and, critically, along the line of flight, explains lead author Benjamin Dix-Matthews, a PhD student at ICRAR and UWA.
