Atomic gas chamber non-magnetic transparent electric heating film preparation method based on laser direct writing

Abstract

The invention relates to a preparation method of a non-magnetic transparent electric heating film of an atomic gas chamber based on laser direct writing, which comprises the following steps of: manufacturing a circuit type micro-pattern on a graphene oxide light-transmitting film with an insulating property by utilizing a laser direct writing reduction technology for performing non-magnetic electric heating around the atomic gas chamber; so that the temperature and the magnetic field of the atomic gas chamber can be more accurately and controllably controlled, and the working effect of the device is more excellent. The two key points of the method are as follows: one is that a novel graphene material is adopted, and the other is that the problems that the existing MEMS silicon heating film is opaque and cannot be directly attached to the atomic gas chamber and the transparent heating film has magnetism are solved.

Problems solved by technology

However, the temperature control accuracy of airflow heating is limited, and the airflow will introduce certain mechanical disturbances

Airflow heating is more suitable for the initial experimental platform. It has the advantages of high heating power and simple implementation. However, for the miniaturized prototype system, its large volume, disturbance introduced by airflow, limited temperature control accuracy and insufficient heating Problems such as uniformity are factors that limit its use

Laser heating is mostly suitable for chip-level atomic sensors. Using non-resonant lasers to heat MEMS gas chambers (MEMS, Micro-Electro-Mechanical System, Micro-Electro-Mechanical System) can avoid the introduction of magnetic field interference in principle, but this The method needs to pay special attention to the interference effect of the heating laser light source, and the heating power is relatively limited, which limits its applicable scenarios to a certain extent, and has certain limitations for the application in miniaturized prototypes
