Description

technical field [0001] The invention belongs to the field of rubidium spectrum lamps, and more specifically relates to an open integrated small rubidium spectrum lamp for miniaturized rubidium atomic frequency standards. Applied to the miniaturized rubidium atomic frequency standard with strict volume requirements, the open and integrated structure makes the rubidium spectrum lamp easy to debug and install. Background technique [0002] As the pumping light source of the physical system, the rubidium spectrum lamp is one of the key components of the rubidium atomic frequency standard, and its performance will affect the overall performance of the rubidium atomic frequency standard. In order to meet the miniaturization design requirements of the rubidium atomic frequency standard, it is necessary to reduce the volume of the rubidium spectrum lamp. [0003] The rubidium spectrum lamp utilizes the principle of electrodeless discharge luminescence of rubidium metal gas. The ex...
