Pre Mode Matching Telescope Parameters, Adaptive Mode matching and Diagnostics

Document #:

LIGO-T0900407-v4

Document type:

T - Technical notes

Abstract:

This document describes the optical parameters and the layout for the pre mode matching telescope for the Advanced LIGO cavities. The decision of specific Gouy phases in the recycling cavities requires mode matching between recycling cavity and the mode cleaner. In this document, we describe the optical layout of HAM2 and the parameters for the pre mode matching telescope. We also describe mode matching diagnostics and adaptive mode matching operation.
