Abstract: The present disclosure relates to a vapor cell and a vapor cell temperature control system, and more specifically, to a vapor cell and a vapor cell temperature control system which use a laser to control the temperature of the vapor cell without distortion of an electromagnetic field. The vapor cell according to an embodiment of the present disclosure may include a body provided with a penetration part, which is a space in which a reactive material is accommodated, and a black material provided on a part of an outer surface of the body. According to an embodiment of the present disclosure, there is an advantage in that the intensity and phase of electromagnetic waves in the micromagnetic field and millimeter wave band can be measured by minimizing distortion and removing noise caused by a temperature control device when measuring electromagnetic fields using an atomic system.
