  • Publication number: 20230350130
    Abstract: A system and method for delivering stable light to a remote location are provided. The method includes splitting a laser beam generated by a laser into a reference beam and a delivery beam. The delivery beam is coupled into an optical fiber for delivery to the remote location. A reflected portion of the delivery beam comes back as a reflected delivery beam from the remote location through the optical fiber. An interference beam is generated by combining the reference beam and the reflected delivery beam. A phase difference between the reference beam and the reflected delivery beam is detected in order to adjust a phase of the laser beam based on the phase difference to reverse a phase shift of the delivery beam induced by noise added to the delivery beam while the delivery beam is transmitted through the optical fiber.

  • Publication number: 20230253753
    Abstract: A laser stabilization system and method are provided. The laser stabilization system includes: a laser configured to produce a laser light signal at a target frequency; a phase modulator configured to apply a phase modulation to the laser light signal to produce a phase modulated laser light signal; a stable optical resonator configured to receive the phase modulated laser light signal and return a light signal; a light detection system configured to receive the light signal from the stable optical resonator and produce an amplitude modulated electrical signal based on the light signal; and a digital domain circuit configured to generate a control signal based on the amplitude modulated electrical signal.

  • Patent number: 10141712
    Abstract: A method for adjusting an optical cavity's length includes: measuring a first absolute frequency corresponding to a cavity mode, the optical cavity having a first and second mirror having respective first and second mirror surfaces separated by a first cavity length, and a resonator body interposed therebetween; determining a length difference between the first cavity length and a target cavity length corresponding to a plurality of resonance frequencies that includes a target absolute optical frequency; removing the first mirror to expose a first end of the resonator body; depositing, on one of the first end and the first mirror, a spacer having a thickness within a length tolerance of the determined length difference; and reversibly securing the first mirror to the resonator body, the spacer being between the first mirror and the resonator body, the first and second mirrors being separated, within the length tolerance, by an adjusted cavity length.
