|Session: Advanced Gravitational Wave Detectors and Advanced LIGO Technology (February 24, 2010)|
Title: Optics for Gravitational Wave Detectors
|Speaker: Gregg Harry|
Optics are at the heart of a gravitational wave detector; among other things they serve as the test masses whose motion is measured. They must satisfy many demanding requirements including low optical absorption, low scatter, high optical power tolerance, precise transmission, and low thermal noise all over very large (100's of square centimeter) areas. I will discuss how both first generation and second generation gravitational wave optics are designed, built, and function. I will also discuss research directions for improving the optics aimed at third generation detectors.
