Abstract
Crystalline silicon is currently being discussed as test-mass material for future generations of gravitational wave detectors that will operate at cryogenic temperatures. We present optical absorption measurements on a large dimension sample of crystalline silicon at a wavelength of 1550 nm at room temperature. The absorption was measured in a high-intensity monolithic cavity setup using the photo-thermal self-phase modulation technique. The result for the absorption coefficient of this sample with a specific resistivity of 11 kOhmcm was measured to be α = (264 ± 39) ppm/cm for an intensity of 700 W/cm.
