Abstract: Methods and systems for controlling and maintaining the pressure in an ultra-stable optical resonance cavity are disclosed herein. A method for controlling and maintaining the pressure in an ultra-stable optical resonance cavity, for example, comprises providing an ultra-stable optical system housed in a vacuum housing enclosure and a pumping system in communication with the vacuum housing for maintaining a pressure in the vacuum housing less than 1×10−6 Torr. The pumping system may comprise combination pumping achieved with the simultaneous use of a getter pump and an ion pump that provide passive and active pumping, respectively. The pumping system may also comprise passive pumping only with a getter vacuum pump only. The present invention, disclosed herein, achieves passive, power-free pumping in ultra-stable laser systems thereby enhancing the portability of such systems.

Abstract: A laser stabilization system for stabilizing a laser beam emitted by a laser includes a phase modulator configured to apply a phase modulation to received laser radiation, an optical cavity configured to receive the phase modulated laser radiation and provide amplitude modulated measurement radiation, and an optical detector configured to generate, based on the amplitude modulated measurement radiation, a radiofrequency electrical signal. A signal distribution network provides a digital branch electrical input signal and an analog branch electrical input signal to a digital control circuit and an analog control circuit, respectively. The digital control circuit generates, based on the digital branch electrical input signal, a first control signal, and the analog control circuit generates, based on the analog branch electrical input signal, a second control signal. An output interface supplies laser control output to the laser based on the first control signal and the second control signal.

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.

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.
