I'm working on the AbsL experiment. A measurement which involved the PRC locked is running at the moment.
Please make sure of not interfering with the interferometer until it is done. Thank you.
I'm done for the moement.
I realized that I need to take into account somehow the DC power from the photodiode. By now the measurement of the transmitted beat's power is affected by the total power circulating inside of the PRC and thus it depends on the cavity alignment.
I closed the laser shutter and turned down the flipping mirrors.
I'm planning to restart measuring by 2.30pm today. Till then the interferometer is available.
