Abstract
We have developed a new photodetector circuit for use in interferometric gravitational wave detectors. The circuit can detect high laser power with low noise and provide multiple outputs for different signal frequencies. The dynamic range of this circuit is increased in comparison with the photodetector design used until the end of 2005.
