Multiple-cavity vapor cell structure for micro-fabricated atomic clocks, magnetometers, and other devices

摘要

An apparatus includes a vapor cell having multiple cavities fluidly connected by one or more channels. At least one of the cavities is configured to receive a first material able to dissociate into one or more gases that are contained within the vapor cell. At least one of the cavities is configured to receive a second material able to absorb at least a portion of the one or more gases. The vapor cell could include a first cavity configured to receive the first material and a second cavity fluidly connected to the first cavity by at least one first channel, where the second cavity is configured to receive the gas(es). The vapor cell could also include a third cavity fluidly connected to at least one of the first and second cavities by at least one second channel, where the third cavity is configured to receive the second material.

主权项

1. An apparatus comprising:
a vapor cell having: a first cavity configured to receive a first material; a second cavity fluidly connected to the first cavity by a first channel, the second cavity configured to receive one or more gases dissociated from the first material and allow radiation to pass through; and a third cavity fluidly connected to one of the first cavity or the second cavity by a second channel, the third cavity configured to receive a second material for absorbing a portion of the one or more gases dissociated from the first material.
