Manufacturing device of integrated optical fiber laser collimator

Abstract

The invention relates to a manufacturing device of an integrated optical fiber laser collimator. The manufacturing device of the integrated optical fiber laser collimator comprises a transparent or netlike upper electrode, a lower electrode, a high-frequency alternating current-direct current power supply, a curing mechanism and a light beam diffusion angle detection device, wherein the middle part of the lower electrode is provided with a through hole and the lower port of the through hole is internally provided with a positioning convex ring; the curing mechanism is provided with an annular ultraviolet light source and is located between the upper electrode and the lower electrode; and the light beam diffusion angle detection device is located above the upper electrode. The collimator disclosed by the invention has a good collimation effect, and can be used for greatly reducing the optical energy loss of the end face and improving the energy transmission threshold value; the device disclosed by the invention combines steps of regulating surface shape of a liquid drop by an electric field, curing a liquid drop by a micro lens and detecting the lens surface shape and the collimation effect in real time, so as to detect the collimated light beam diffusion angle in real time, guarantee the synchronization of manufacturing and detecting, and reduce the rejection ratio.

Description

technical field [0001] The invention belongs to the technical field of laser optical fibers, and in particular relates to a manufacturing device of an integrated optical fiber laser collimator. Background technique [0002] In the existing laser fiber collimator, the method of gluing the collimating lens and the end face of the fiber is usually adopted, and the prepared self-focusing lens, aspheric lens, spherical lens or lens group is glued on the end face of the fiber. The collimator produced by the method has the following problems: 1. There are installation and adjustment errors, which affect the collimation effect; 2. The adhesive in the optical path is easily damaged in high-power lasers; 3. The detection and production are not synchronized, and it is difficult to control the collimator Precision, high reject rate. In order to improve the performance of the collimator, a lot of research work has been done. For example, the Chinese patent "New Optical Fiber Collimator...
