Squeezed light for advanced gravitational wave
... The squeezed beam experiences losses in the optical path from the squeezed light source to the interferometer readout photodetector (see Fig. 2). These losses are typically caused by imperfections in optical surfaces and polarizing optics (such as Faraday Isolators), and by imperfect spatial overlap ...
