Abstract
A physics package includes a laser, a first vapor cell having an alkali metal vapor and a first buffer gas, a second vapor cell having the alkali metal vapor and a second buffer gas, and a photo-detector. The first and second buffer gases differ. A first and a second portion of the laser output traverse the first vapor cell and second vapor cell, respectively. The photo-detector detects a first optical transmittance and a second optical transmittance of the portions of the laser transmitted through the first vapor cell and the second vapor cell, respectively. A system includes the physics package, an output frequency generator, a microwave generator, a circuit to modulate the laser output, and a control circuit. The control circuit modulates a characteristic of the laser output and controls the frequency generator output. The system may compensate for a temperature change in the physics package.
