Processing method for improving anti-radiation performance of quartz optical fibers

Abstract

The invention relates to a processing method for improving anti-radiation performance of quartz optical fibers. Quartz optical fiber materials are high-pure quartz materials. The processing method adopts methods of a preheating treatment, rapid quenching, and pre-radiation and a re-preheating treatment. The preheating treatment is that the temperature is maintained in a certain range to make the structure of quartz optical fiber materials more stable. Rapid cooling makes sure that the structure of the quartz optical fiber materials remains in stable at the room temperature. Pre-radiation is that pure quartz optical fiber materials are subjected to a certain amount radiation to break the fatigue bonds of the pure quartz fiber optical material to give off redundant power. The re-preheating treatment makes the broken bonds pre-radiated recover so as to form stable structures. The anti-radiation quartz optical fiber materials, which are produced according to the processing method for improving anti-radiation performance of quartz optical fibers, have a very good anti-radiation performance and a very good anti-radiation effect under a very high radiation dose. The anti-radiation quartz optical fiber materials not only can be used for the production of optical fibers, but also can be used for the production of related devices made of anti-radiation quartz materials.

Description

technical field [0001] The invention relates to a processing method for improving the anti-radiation performance of a quartz optical fiber, which belongs to the field of optical communication. Background technique [0002] With the continuous development of nuclear technology and space technology, silica fiber materials and devices are more and more widely used in radiation-related fields. However, the performance of conventional silica fiber materials and devices will be greatly affected in the radiation environment. For example, the transmission loss of silica fiber materials will increase, resulting in a decrease in the ability of the fiber to transmit signals. In severe cases, it will directly affect the performance of the fiber during use. Safety and reliability; devices made of silica fiber material will also fail. For this reason, studying the characteristics of silica fiber materials in various radiation environments and trying to reduce their radiation sensitivity ...
