In the name of this file, '00' means % the TEM00 mode and hence these are the probes dedicated only for % the length sensing and not for angular sensing. % Example usage : % par = paramC1; % opt = optC1(par); % opt = probesC1_00(opt, par); %-------------------------------------------------------- % % [Notes] % This file is a modified version of the eLIGO opticle file % called probesH1_00.m. % function opt = probesC1_00(opt, par) % Add attenuators and terminal sinks % Here the second return value of the addSink function is used. % This return value is the serial number of the Sink, which is % can be used in place of its name for linking (with a marginal % increase in efficiency). % 3rd addSink argument is power loss, default is 1 % Attenuator set to match what is there in the real IFOs, maybe. % AS: transmission to the dark port from SR, before the OMC % 'Att' stands for 'Attenuation' opt = addSink(opt, 'AttREFL', 0); opt = addSink(opt, 'AttAS', 0); opt = addSink(opt, 'AttPOP', 0); opt = addSink(opt, 'AttPOX', 0); opt = addSink(opt, 'AttPOY', 0); [opt, nREFL] = addSink(opt, 'REFL'); [opt, nAS] = addSink(opt, 'AS'); [opt, nPOP] = addSink(opt, 'POP'); [opt, nPOX] = addSink(opt, 'POX'); [opt, nPOY] = addSink(opt, 'POY'); [opt, nTRX] = addSink(opt, 'TRX'); [opt, nTRY] = addSink(opt, 'TRY'); % Output links, set gouy phases %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Function addReaduotGouy set the gouy phase 90 degrees apart % NB: Demodulation phases are in degrees, gouy phases in radiants!!
