 Abstract: Wavefront distortion due to absorption in the substrates and coatings of mirrors in advanced gravitational wave interfbrometers has the potential to compromise the operation and sensitivity of these intern ferometers [Opt. Lett. 29, 2635-2637 (2004)]. We report the first direct spatially-resolved measurement, to our knowledge, of such wavefront distortion in a high optical power cavity. The measurement was made using an ultrahigh sensitivity Hartmann wavefront sensor on a dedicated test facility. The sensitivity of the sensor was lambda/730, where lambda = 800 nm.
