Presenters: Ms Georgia Mansell, Australian National University

Advanced LIGO (laser interferometer gravitational wave observatory) is the most sensitive displacement metrology experiment in the world, consisting of two Michelson interferometers with optical cavity arms each at 4 km in length. Last year the LIGO scientific collaboration announced the first observation of gravitational waves, from a binary black hole merger. The injection of squeezed states of light will further enhance the detectors’ astrophysical reach by improving sensitivity beyond shot noise. In this talk, I will summarize the research efforts towards a squeezed light source for advanced LIGO. I will also talk about the recent research into squeezed light sources in the 2 micron region, for potential future gravitational wave detectors.
