PHYSICS WORLD - Future versions of the Laser Interferometer Gravitational Wave Observatory (LIGO) will be able to run at much higher laser powers thanks to a sophisticated new system that compensates for temperature changes in optical components. Known as FROSTI (for FROnt Surface Type Irradiator) and developed by physicists at the University of California Riverside...
INTERESTING ENGINEERING - Gravitational waves, tiny ripples in spacetime caused by cosmic collisions like merging black holes, are almost impossibly faint. Detecting them requires LIGO (Laser Interferometer Gravitational-Wave Observatory), one of the most sensitive instruments ever built. However, there’s a catch. To see farther and catch weaker signals, LIGO needs more powerful lasers, but stronger...
