Abstract

The utility model discloses a kind of optical-fiber bundling devices, including drawing taper bushing, the one group of optical fiber drawn in taper bushing being arranged in, as an improvement, the drawing taper bushing includes two layers of quartz glass sleeve.It includes two layers of quartz glass sleeve that the utility model, which draws taper bushing, and the double-deck quartz glass sleeve is in order to forming the emission layer of light.Taper bushing front end is drawn to be equipped with isodiametric stretch section, front end equal diameter stretch section simplifies the subsequent processing of bundling device.The double-deck quartz of the utility model draws taper bushing and equal diameter stretch section, and structure formation leads beam optical path, when closing beam multi-mode laser, the diameter of output facula greatly reduced, to enhance density energy.

Description

A kind of optical-fiber bundling device

Technical field

The utility model relates to a kind of optical-fiber bundling devices.

Background technique

With the development of semiconductor light fibre laser, high-power laser output, laser all over the world are special in order to obtain Industry has all started the upsurge of the high performance optical-fiber bundling device of development, and the bundling device of various schemes is all being come out one after another, in general, The conjunction beam efficiency and manufacture craft of bundling device are always a bottleneck, and key is that the diameter very little of energy optical fiber (usually exists Between 0.1-0.4 millimeters), and carried out under the environment of high temperature cleaning, production is got up, and there are biggish difficulty, so general Draw pitch cone radius from shorter, the centrum gradient is big, causes energy loss big.

Existing fiber bundling device draws taper bushing structure and gradient setting not reasonable, and optical fiber is caused to draw energy at taper bushing In transmission process, energy loss is excessive.Optical fiber needs to be arranged connection tail optical fiber, to improve output facula quality, the work simultaneously Skill requires stringent complexity, and one-time success rate is low.

Summary of the invention

The utility model be solves the problems, such as that the prior art exists in use, provide one kind it is structurally reasonable, be easily installed The optical-fiber bundling device used.

The technical solution that the utility model solves existing issue is: a kind of optical-fiber bundling device, including taper bushing, arrangement is drawn to set What is be placed in draws one group of optical fiber in taper bushing, as an improvement, the drawing taper bushing includes two layers of quartz glass sleeve.

As a further improvement, the drawing taper bushing front end is equipped with isodiametric stretch section.

As a further improvement, the drawing taper bushing draws coning angle to be not more than 0.15 °.

As a further improvement, one group of optical fiber includes at least three optical fiber, the every optical fiber is individually to draw The drawing coning angle for drawing coning angle and drawing taper bushing of the optical fiber of cone, one group of tapered fiber is adapted.Above-mentioned optical fiber is drawn Coning angle is not more than 0.15 °.

Compared with prior art, drawing taper bushing includes two layers of quartz glass sleeve, the beneficial effect is that, The double-deck quartz glass sleeve is in order to forming the reflecting layer of light.

Further, taper bushing front end is drawn to be equipped with isodiametric stretch section, front end equal diameter stretch section simplifies bundling device Subsequent processing.

The double-deck quartz of the utility model draws taper bushing and equal diameter stretch section, and beam optical path is led in structure formation, closes Shu Duomo and swashs Light time has greatly reduced the diameter of output facula, to enhance density energy.

Specific embodiment

Referring to Fig. 1-6, the implementation case includes drawing taper bushing 1, the one group of optical fiber drawn in taper bushing being arranged in 2, drawing taper bushing 1 includes the casing of internal layer 12, two layers of the quartz glass of outer layer 13 composition.

1 front end of taper bushing is drawn to be equipped with isodiametric stretch section 11.

One group of optical fiber 2 includes compact arranged at least three optical fiber, and every optical fiber 2 is the optical fiber for individually drawing cone, one group of drawing The drawing coning angle for drawing coning angle and drawing taper bushing for boring optical fiber is adapted.

See Fig. 5,6, in the implementation case, one group of optical fiber 3 is for seven, and seven close fiber optics arrangements, 6 are drawn the light of cone Fibre surrounds intermediate one, and every optical fiber and casing draw cone at angle appropriate respectively, after optical fiber puts on casing, carry out high warm It is molten, constitute fiber optic bundle.Equal uniaxial direct tensiles are carried out to the casing of front end after molding, constitute stretch section 11, self-assembling formation leads beam optical path, It does not need to connect tail optical fiber, can uniformly conduct well, so that hot spot optical intensity density is consistent.

In general, drawing the smaller of the smaller energy loss of the gradient of cone, the drawing of taper bushing 1 and every optical fiber is drawn in the implementation case Coning angle is not more than 0.15 °.
