Abstract

The invention discloses a preparation method of a transparent ceramic optical fiber with a core-spun structure, wherein the method comprises the steps: firstly preparing a prepared ceramic paste Re:M into a transparent ceramic optical fiber by adopting a 3D printing direct-writing rapid prototyping machine, then carrying out treatment procedures of surface treatment, chemical nickel plating, heat treatment and nickel pre-plating, and finally electroplating copper on the ceramic surface of a nickel pre-plating layer. The core layer ceramic paste and the metal layer are effectively compounded on the basis of an electroplating technology, and then the transparent ceramic optical fiber material with the high length-diameter ratio is prepared by combining the processes of low-temperature degreasing, high-temperature vacuum treatment, post-treatment and the like.

Description

technical field [0001] The invention relates to the technical field of preparation of ceramic optical fibers, in particular to a preparation method of a transparent ceramic optical fiber with a core-clad structure. Background technique [0002] As a new type of optical functional inorganic material, laser ceramics have been regarded as an effective gain medium for high-power solid-state lasers instead of single crystals, because of their good mechanical properties, thermal properties and optical properties. years has received widespread attention. However, when transparent ceramics are subjected to high-power pump light, the thermal effect generated by absorbing a large amount of pump light inside the material also becomes a key bottleneck restricting its better application. The thermal management and regulation methods of traditional laser materials have problems such as high-load operation and insufficient heat dissipation. The traditional cooling method will inevitably ...
