Embodiment 1

[0027] see first figure 1 , figure 1 It is a schematic diagram of a device in which three optical fiber bundles are inserted into a capillary in Example 1 of the present invention. As can be seen from the figure, the device for fast penetration of multiple optical fiber bundles into capillaries of the present invention includes an optical fiber bundle positioning fixture 1, an annular pre-constrained fixture 8, a quartz capillary 9 and a linear displacement platform, and the optical fiber bundle positioning fixture 1 consists of a uniform Three distributed V-shaped clamping grooves and one-to-one corresponding three fixed pressing blocks 2, 3, 4 are formed. The ring-shaped clamping part of the annular pre-constraint fixture 8 reserves three optical fibers into an optical fiber bundle. The quartz capillary 9 is positioned in the V-groove of the V-groove capillary clamp 10, the quartz capillary 9 is fixed on the linear displacement platform through the V-groove fixed capillary ...

Embodiment 2

[0037] see figure 2 , Figure 4 and Figure 6 , the method of embodiment 2 is as follows:

[0038] 1) First remove the coating layer at one end of the seven optical fibers to form the end of the bare optical fiber, and then place multiple optical fibers in sequence in the V-shaped clamping groove in the optical fiber positioning fixture 1 for clamping;

[0039] 2) The ends of the bare optical fibers are pre-constrained by the ring-shaped clamping part of the annular pre-constraint fixture 8, so that the outer diameters of the ends of the bare optical fiber bundles are tangent, and closely arranged to form a uniformly arranged circular optical fiber bundle;

[0040] 3) The quartz capillary 9 is positioned in the V-groove of the V-groove positioning fixture 10, and the quartz capillary 9 is fixed on the linear displacement platform by the V-groove positioning fixture 10. The laser beam adjustment tool, the centerlines of the optical fiber positioning fixture 1, the optical ...

Abstract

The present invention provides a device of fiber optics bundles penetrating a quartz capillary and a penetrating method thereof. The device comprises a fiber optics bundle location clamp, an annular pre-constraint clamp, a quartz capillary and a linear displacement platform in order. The device of fiber optics bundles penetrating a quartz capillary and the penetrating method thereof solve the problem of difficult location and arrangement of the optical fibers and the fracture problem generated when the fiber optics bundles penetrate the quartz capillary so as to improve the success rate of thefiber optics bundles penetrating the quartz capillary and provide reliable guarantee for bundling process devices such as an optical fiber beam combiner and a coupling device.

Description

technical field [0001] The invention relates to a beam combiner, in particular to a device and a method for penetrating a plurality of optical fiber bundles into a quartz capillary. Background technique [0002] With the development of laser application technology, the fields of space communication, laser weapons, material processing, remote sensing and lidar have put forward an urgent demand for high-power and high-beam quality lasers. Fiber lasers have the characteristics of compact structure, convenient thermal management, good beam quality and high conversion efficiency, and have been widely used in the field of high-power lasers. [0003] Fiber combiner is one of the core components in fiber oscillator and fiber laser amplifier. Its main implementation methods include end-pumping technology (such as an N×1 fiber combiner with patent application number 200420074890.2) and side pumping technology (such as double-clad fiber laser side-pump coupling with patent application...
