Improving the sensitivity of Advanced LIGO with squeezed light

Presenting Author: Lee McCuller, Massachusetts Institute of Technology
Contributing Author(s): The LIGO laboratory squeezing team

The upcoming observing run 3 of Advanced LIGO will include quantum squeezed light at both observatories to improve sensitivity. This talk will detail the ongoing commissioning, as well as the technical requirements driving the design and control of audio-band squeezed light sources for gravitational wave optical interferometers. In addition, R&D is ongoing to demonstrate frequency dependent squeezed vacuum at 50Hz using optical filter cavities. Such an implementation will allow LIGO to reduce quantum radiation pressure noise below the standard quantum limit to achieve improvements spanning its observation band.
