Optical integrated high-power optical energy transmission assembly

Abstract

The invention discloses an optical integrated high-power optical energy transmission assembly which is composed of three parts, namely an input end coupling part, an optical fiber and an output end coupling part which are integrated together through an optical integration technology to form an optical part. The outer diameter of the input end coupling part is gradually reduced from the open end to one end close to the optical fiber, and the outer edge contour of the input end coupling part is in a quadratic function curve shape. Through the optical integration technology, the high-power optical fiber is successfully integrated with the coupling parts at the input end and the output end, the interface and the boundary of the high-power optical fiber and the coupling parts at the two ends are eliminated, and light energy reflection and scattering on the interface between the high-power optical fiber and the coupling parts at the two ends are eliminated; and a high-order mode is effectively prevented from escaping to an external organic strength protection structure, the transmission efficiency of high-power light energy is greatly improved, and a circulating water cooling system does not need to be used.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to an optical integrated high-power optical energy transmission component. Background technique [0002] Optical fiber used for communication is a great invention of the last century, and the application of optical fiber is rapidly developing into other technical fields. High-power optical fiber is a new technology in the field of optical fiber. High-power optical fiber can not only transmit powerful optical signals, but also transmit powerful optical energy and powerful laser energy. The development of high-power optical fiber technology has promoted the development of industrial laser processing technology, military laser technology and laser medical treatment and other multi-field laser technology. The high-power optical fiber products manufactured by optoskand and the crystal structure high-power optical fiber produced by Liaoning Weier Quantum are both high-power optica...

[0007] 2. Low coupling efficiency between optical waveguide and injected light

It is difficult and inefficient to inject a 6mm spot into a 1mm fiber

In order to improve the coupling efficiency as much as possible, a piece of quartz glass block polished into a tapered shape is fused at the top of the optical fiber. After fusing a quartz glass block, the coupling efficiency of the injected light is significantly improved, but there must be an interface in the fusion, not to mention The material properties and glass structure of the quartz glass block cannot be exactly the same, and there is a difference in refractive index
