¶ Input Mode Cleaner
A suspended triangular optical cavity between the laser (and pre-mode cleaner) and the main interferometer. Its purpose is to clean the input light of higher order modes, increase the frequency stabilization of the light, etc. For the IMC layout and location see this H1 optical layout (update with L1 layout).
The first integration phase for the Advanced LIGO L1 interferometer is the commissioning of the Input Mode Cleaner (IMC), the Faraday Isolator (FI), the auxiliary input optics (IO), and the power recycling cavity optics located in the HAM2 and 3 vacuum chambers, using the light beam from the Pre-Stabilized Laser (PSL). The integrated testing of the PSL/IMC/IO began in June of 2012.
