  • 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.

  • Patent number: 7469454
    Abstract: A technique for reducing the vibration sensitivity of laser-stabilizing optical reference cavities is based upon an improved design and mounting method for the cavity, wherein the cavity is mounted vertically. It is suspended at one plane, around the spacer cylinder, equidistant from the mirror ends of the cavity. The suspension element is a collar of an extremely low thermal expansion coefficient material, which surrounds the spacer cylinder and contacts it uniformly. Once the collar has been properly located, it is cemented in place so that the spacer cylinder is uniformly supported and does not have to be squeezed at all. The collar also includes a number of cavities partially bored into its lower flat surface, around the axial bore. These cavities are support points, into which mounting base pins will be inserted. Hence the collar is supported at a minimum of three points.
