The parameters in this section refer to the Advanced LIGO experiment. The primary interferometer consists of two beam lines of 4 km length which form a power-recycled Michelson interferometer with Gires–Tournois etalon arms. A pre-stabilized 1064 nm Nd:YAG laser emits a beam with a power of 20 W that passes through a power recycling mirror. The mirror fully transmits light incident from t… Nettet4. mar. 2013 · Mar 4, 2013.

NettetThe use of Fabry-Pérot cavities makes so that the light can be trapped inside the arm for many round trips, before being reflected back or transmitted: this causes the big advantage that the effective arm length of the interferometer is amplified by a factor 2 F π ≈ 300 (where F ≈ 460 is the Finesse of the arm cavities), therefore increasing the detector …
