Active Reduction of Residual Amplitude Modulation in Free Space EOMs

Document #:

LIGO-T1900242-v2

Document type:

T - Technical notes

Abstract:

Our goal is to use an EOM as a phase modulator in a cavity-stabilized laser system and create a feedback mechanism by controlling the temperature and DC bias of the EOM to actively suppress RAM to the level of 1x10^-5.
