Increasing the sensitivity of next-generation gravitational wave detectors

Nearly one year ago today, the LIGO Collaboration announced the detection of gravitational waves, once again confirming Einstein’s theory of General Relativity. This important discovery by the Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO) has spurred great interest in improving these advanced optical detectors. The mission of gravitational wave scientists worldwide is to make gravitational wave detection a routine occurrence. Scientists from the institute that developed the lasers used in Advanced LIGO have made significant progress to support that goal.
