Doped solution spraying device and method

Abstract

The invention provides a doped solution spraying device and method, the doped solution spraying device comprises a solution storage device, a guide pipe, a sprayer, a hard hollow pipe, a quartz reaction pipe, an electric lifting platform, a guide rail, a speed sensor, a nitrogen conveying pipe with a pressure regulating valve and a support seat, one end of the hollow pipe is connected with the solution storage device, the other end is connected with the solution spraying device, the solution storage device controls the pressure of a solution and conveys the solution at a constant speed, the feeding speed is controlled by controlling nitrogen conveying, and an ionic solution flows out through the hard hollow pipe 4, enters the sprayer to be sprayed out, receives the speed sensor in real time and obtains the position information of the sprayer through calculation. An ionic solution is sprayed into the quartz reaction tube for multiple times through the reciprocating motion of the electric lifting platform. The device has the advantages of being simple in structure, convenient to operate, high in controllability and capable of doping various ionic solutions with different concentrations. The optical fiber qualification rate and the optical fiber loss are improved, the light beam quality of the optical fiber laser is improved, and use requirements in various aspects are met.

Description

technical field [0001] The invention relates to an optical fiber preform rod preparation device, in particular to a doping solution spraying device and a spraying method. Background technique [0002] With the development of laser technology, lasers are more and more widely used in military and civil affairs. At the same time, the requirements for lasers are getting higher and higher. High quality, high power and high efficiency are important criteria for judging the quality of lasers. In recent years, laser fiber lasers doped with rare earth ions have gradually attracted everyone's attention because of their advantages such as good beam quality, small size, fast speed, and long working life. And it has been widely used in the field of laser welding, medical field, laser communication and many other fields. [0003] The core part of the laser fiber laser is the rare earth ion-doped optical fiber. The optical fiber preform doped with rare earth ions is an essential part of d...

Problems solved by technology

However, since the chelate itself contains carbon elements, it is easy to generate carbon deposition, resulting in higher loss of optical fiber

And the gas-phase doping method requires saturated gaseous reactants, a slight decrease in temperature will condense the gaseous reactants into a solid state, do not participate in the reaction, and easily block the pipeline
