NOISE-INDUCED BY LASER POWER FLUCTUATIONS VIA ABSORPTION ASYMMETRY INGRAVITATIONAL-WAVE INTERFEROMETRIC DETECTORS

Coupling between asymmetry in absorption and laser power fluctuations may be a source of noise in gravitational-wave interferometric detecto rs. This effect is negligible for the first generation of detectors su ch as LIGO/VIRGO, but attention should be paid to the reproducibility of the thermal parameters in the next generation, where the noise we c onsider could be comparable to the shot noise.
