Sean Leavey and Harald Lück At the prototype we use a lithum niobate New Focus (now Newport) 4004 broadband electro-optic modulator (EOM) as part of our reference cavity frequency stabilisation servo. During measurements we noticed that the EOM contained high-Q resonances at around 790 kHz and 2 MHz which looked mechanical in origin: These resonances […]
