First results of a high sensitivity and transportable Ring Laser Gyroscope
arXiv:2606.02594v1 Announce Type: new Abstract: Within the frame of the GINGER project, aimed at installing an array of large frame ring laser gyroscopes for fundamental physics tests and as part of a geophysics observatory located in the underground laboratory at Gran Sasso, Italy (LNGS-INFN), we are developing a ring laser gyroscope design to reduce spurious rotation of instrumental origin and the ability to extend the cavity perimeter from 1.5 up to 5m, thanks to the implementation of...
Ultralow shot noise limited giant passive resonant gyroscope for Earth rotation measurement
Announce Type: new Abstract: Optical gyroscopes directly measure the Earth's rotation and are promising instruments for real-time geophysical observations and Earth orientation parameter (EOP) determination requiring both high precision and high temporal resolution. Large-scale ring laser gyroscopes (RLGs) currently reach rotational resolutions around $10^{-11}\,\mathrm{(rad/s)/\sqrt{Hz}}$, but their quantum noise limits make it challenging to meet the requirements of future...
