Abstract

The invention discloses a preparation method of a laser transparent ceramic optical fiber with a waveguide structure based on an Isobam gel-state dip-coating technology. The preparation method comprises the following steps: preparing a core layer of an Nd: YAG transparent ceramic optical fiber by using a gel forming technology; conducting coating of cladding YAG transparent gel slurry in a core gel state (at an intersection point of an elastic modulus and a viscous modulus) by using the gel state dip-coating technology, thereby achieving effective adhesion of a core layer and the cladding, wherein coating thickness is adjusted through time; and finally, conducting warm isostatic pressing and vacuum sintering to prepare the laser transparent ceramic optical fiber with the waveguide structure. By accurately controlling a gel point in the gel state, effective bonding of the core layer and a cladding ceramic material is realized, an interface is clear, and the method is simple and efficient in process and capable of realizing batch and industrial production.

Description

Technical field[0001]The invention relates to the technical field of transparent ceramic optical fiber preparation, in particular to a method for preparing a waveguide structure laser transparent ceramic optical fiber based on Isobam gel state dip coating technology.Background technique[0002]At present, fiber lasers generally use rare-earth-doped glass fibers as gain media. The basic principle is that the power density rises in the fiber under the action of the pump light, causing the laser energy level of the laser working substance to "populate population inversion. The laser oscillation output can be formed in the resonant cavity. Fiber lasers have a wide range of applications, including laser fiber communications, laser space telecommunication, industrial shipbuilding, automobile manufacturing, laser engraving, laser cutting, printing rollers, metal and non-metal drilling / cutting / welding, military and national defense security, Medical equipment can also be used as pump sources ...
