Existing microfabricated atomic vapor cells have only one optical channel,which is insufficient for sup-porting the multiple orthogonal beams required by atomic devices.In this study,we present a novel wafer-level manufacturing process for fabricating multi-optical-channel atomic vapor cells and an inno-vative method for batch processing the inner sidewalls of millimeter glass holes to meet optical channel requirements.Surface characterization and transmittance tests demonstrate that the processed inner sidewalls satisfy the criteria for an optical channel.In addition,the construction of an integrated process-ing platform enables multilayer non-isothermal anode bonding,the filling of inert gases,and the recovery and recycling of noble gases.Measurements of the absorption spectra and free-induction decay signals of xenon-129(129Xe)and xenon-131(131Xe)under different pump-probe schemes demonstrate the suit-ability of our vapor cell for use in atomic devices including atomic gyroscopes,dual-beam atomic mag-netometers,and other optical/atomic devices.The proposed micromolding technology has broad application prospects in the field of optical-device processing.
