Practical speed meter designs for quantum nondemolition gravitational-wave interferometers


In the quest to develop viable designs for third-generation optical interferometric gravitational-wave detectors ~e.g., LIGO-III and EURO!, one strategy is to monitor the relative momentum or speed of the test-mass mirrors, rather than monitoring their relative position. A previous paper analyzed a straightforward but impractical design for a speed-meter… (More)
