ITM03 HR AR Absorption

Document #:

LIGO-E1400010-v2

Document type:

E - Engineering documents

Abstract:

ITM03 HR and AR coating absorption measurements at Caltech OTF.
These measurements taken AFTER removal from LHO O2 aLIGO run. These measurements taken without cleaning the optic, though the optic was cleaned in-situ at LHO.

Absorption of Halos refer to those shown in G1800345
