Calibration of the Glasgow 10 m prototype laser interferometric gravitational wave detector using photon pressure

We show that the radiation pressure from an amplitude modulated, low power, Nd:YAG laser can be used to calibrate the displacement sensitivity of the Glasgow 10 m prototype gravitational wave detector. This demonstrates the possibility of radiation pressure being used as a standard method of calibra...

Description
Summary:We show that the radiation pressure from an amplitude modulated, low power, Nd:YAG laser can be used to calibrate the displacement sensitivity of the Glasgow 10 m prototype gravitational wave detector. This demonstrates the possibility of radiation pressure being used as a standard method of calibrating long base line gravitational wave detectors. Further, this technique has the very important additional advantage that the test mass acted upon by the radiation pressure is not altered in any way, by, for example, the attachment of magnets, etc. The high Q-factor of the internal modes, required for good detector sensitivity, is therefore preserved.
