A new helium-neon laser for the maintenance of optical communication network is designed. The electro-optic crystal and glass plate are regarded as the core modulating devices of He-Ne laser. The structure of the He-Ne laser is given. The application of He-Ne laser in Optical communication network principle. The overall structure of He-Ne laser hardware is given, including ARM microprocessor, He-Ne laser power supply and cavity ring-down loss measurement module. At the time of software design, the control flow of He-Ne laser used in the maintenance of optical communication network is introduced, which is introduced into the ARM microprocessor chip to complete the control of the He-Ne laser. The experimental results show that the designed laser can effectively control and maintain the gain coefficient and maintain the optical communication network with high performance.
