So called q-parameter in the unit of m. Although there is no PRM in iKAGRA, this is a beam parameter at the position where the AR surface of the PRM will be located in bKAGRA. This parameter gives the perfect mode match to the iKAGRA arm cavities. However, the MIF does not require IOO to provide 100% mode matching in iKAGRA phase. |
