Paper Abstract

High levels of mode matching are required for optimal performance in interferometric gravitational wave detectors that use squeezed light injection. We propose a technique for measuring the magnitude and direction of mode mismatch by inducing a radio frequency waist size and position modulation and demodulating the reflected field using a single element photodiode.
