Artist’s concept of gravitational waves propagating through space.
New laser breakthrough to help increase understanding of gravitational waves.
Scientists have created a proof-of-concept setup of a new laser eigenmode sensor that offers over 1,000 times the sensitivity. After translating this work to gravitational wave detectors, they will offer the unprecedented precision needed to test the fundamental limits of general relativity and probe the interiors of neutron stars.
Gravitational wave scientists from The University of Western Australia (UWA) have led the development of a new laser mode sensor with unprecedented precision that will be used to probe the interiors of neutron stars and test the fundamental limits of general relativity.
Research Associate from UWA’s Center of Excellence for Gravitational Wave Discovery (OzGrav-UWA) Dr. Aaron Jones, said UWA co-ordinated a global collaboration of gravitational wave, metasurface, and photonics experts to pioneer a new method to measure structures of light called “eigenmodes.”
“Gravitational wave detectors like LIGO, Virgo, and KAGRA store enormous amount of optical power, and several pairs of mirrors are used to increase the amount of laser light stored along the massive arms of the detector,” Dr. Jones said. READ MORE...
