A first apparatus includes a vapor cell having first and second cavities fluidly connected by multiple channels. The first cavity is configured to receive a material able to dissociate into one or more gases that are contained within the vapor cell. The second cavity is configured to receive the one or more gases. The vapor cell is configured to allow radiation to pass through the second cavity. A second apparatus includes a vapor cell having a first wafer with first and second cavities and a second wafer with one or more channels fluidly connecting the cavities. The first cavity is configured to receive a material able to dissociate into one or more gases that are contained within the vapor cell. The second cavity is configured to receive the one or more gases. The vapor cell is configured to allow radiation to pass through the second cavity.
