Abstract

Electrostatic charging of the mirrors and suspensions in interferometric gravitational wave detectors may compromise aspects of both the sensitivity and control of current and planned instruments. The use of conductive coatings of tin (II) oxide as a possible charge mitigation technique is investigated here, where we report measurements of the optical loss and mechanical loss for the first time at frequencies of interest for gravitational wave detection.
