Frequency locking of multiple lasers to an optical cavity Article uri icon

abstract

  • We demonstrate the locking of multiple lasers to an ultralow expansion cavity using a single fiber electro-optical modulator. We use this modulator to lock the frequency of one of the sidebands to the cavity resonance using an extension of the Pound-Drever-Hall technique. The frequency of the carrier can be tuned by changing the sidebands%27 separation. We distinguish the signal coming from different lasers by their modulation frequency in the demodulation. The scheme is scalable to a large number of lasers without requiring extra optical components. © 2018 Optical Society of America.
