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: In an aspect, a pressure sensor for determining pressure in an environment comprises: a source for emitting a coherent reference light characterized by a reference light frequency; a first lock-in mechanism configured to send an electrical signal to the source based on a reference resonance frequency; a reference cavity; wherein the reference cavity is characterized by the reference resonance frequency; a modulator configured a reference light to generate at least a first sideband frequency such that an output of said modulator is a measurement light characterized by at least the first sideband frequency; a frequency synthesizer configured to drive the modulator; a second lock-in mechanism configured to send an electrical signal to the frequency synthesizer based on a measurement resonance frequency; and a measurement cavity configured to receive at least a portion of the measurement light; wherein the measurement cavity is characterized by the measurement resonance frequency; and wherein the pressure of the environment is determined based on the reference resonant frequency and the measurement resonance frequency.
