Specific implementation mode
The invention will be further described with reference to the accompanying drawings and embodiments.
As shown in Fig. 1-Fig. 6, high-power optical fiber coupler encapsulating structure part provided by the invention includes top fixed structure
Part 1, lower part light guide structure part 2 and guide-lighting crystal block 3；Wherein guide-lighting crystal block 3 is semicolumn body structure；Top fixed structure
Part 1 is cuboid structure, is recessed along its length in the middle part of bottom surface and is formed with a row groove, wherein intermediate position is D-shaped center
Inner groovy 4, outermost are two D-shaped screw thread inner groovies 5, are one between each D-shaped screw thread inner groovy 5 and D-shaped center inner groovy 4
A D-shaped inner groovy small stair 6, input optical fibre 7 and output optical fibre 8 in high-power optical fiber coupler cone are separately fixed at two
On D-shaped inner groovy small stair 6, and the outer end of input optical fibre 7 and output optical fibre 8 respectively by two D-shaped screw thread inner groovies 5 to
Outer extraction；The above-mentioned reeded central axis of institute is located at same straight line, while D-shaped center inner groovy 4, D-shaped screw thread inner groovy 5
It is sequentially reduced with the internal diameter of D-shaped inner groovy small stair 6；Lower part light guide structure part 2 it is identical with the structure of top fixed structure piece 1 and
Mirror each other, top fixed structure piece 1 are covered in the surface of lower part light guide structure part 2；Guide-lighting crystal block 3 is fixed on lower part
In the D-shaped center inner groovy 4 of light guide structure part 2；The contact surface of top fixed structure piece 1 and lower part light guide structure part 2 utilizes close
Sealing seals.
D-shaped inner groovy small stair 6 and D-shaped center indent in the top fixed structure piece 1 and lower part light guide structure part 2
The surface roughness of slot 4 is that can debate processing direction Ra0.8, it is therefore an objective to enhance high-power optical fiber coupler provided by the invention
Scattering of the encapsulating structure part surface to light.
Now the encapsulation process of high-power optical fiber coupler encapsulating structure part provided by the invention and application method are illustrated such as
Under：Utilize index matching UV optical cements by the input light in high-power optical fiber coupler cone by staff first when assembling
Fibre 7 and output optical fibre 8 are separately fixed on two D-shaped inner groovy small stairs 6 of top fixed structure piece 1, due to D-shaped inner groovy
The internal diameter of small stair 6 is less than the internal diameter of D-shaped screw thread inner groovy 5 and D-shaped center inner groovy 4, so high-power optical fiber coupler is bored
The intermediate position of body and outside left are in vacant state, are conducive to radiate, burn high power to prevent thermal energy from excessively concentrating
Fiber coupler cone.Then guide-lighting crystal block 3 is fixed on to the D-shaped center indent of lower part light guide structure part 2 using fluid sealant
In slot 4.Top fixed structure piece 1 is covered in the surface of lower part light guide structure part 2 later, contact surface application fluid sealant carries out close
Envelope processing, then top fixed structure piece 1 and lower part light guide structure part 2 are fixed together with screw.Finally utilize epoxy UV glue
The external port of D-shaped screw thread inner groovy 5 in top fixed structure piece 1 and lower part light guide structure part 2 is sealed up, Gao Gong is thus completed
The entire encapsulation process of rate fiber coupler encapsulating structure part.Pay attention in encapsulation process, since high-power optical fiber coupler is bored
Body belongs to superlaser family device, so the fixed position to high-power optical fiber coupler cone is needed to be detected, observes
Whether impurity is had.In addition, this high-power optical fiber coupler encapsulating structure part, which is suitable only for encapsulation, can transmit pumping laser general power
In 1500W high-power optical fiber coupler cones below, pumping laser general power 1500W or more can be transmitted if necessary to encapsulate
High-power optical fiber coupler cone, then need the thickness for increasing guide-lighting crystal block 3, and water cooling conduit is added in thicken position,
It is radiated by the way of indirect water-cooling.
In use, since the D-shaped center inner groovy 4 in top fixed structure piece 1 and lower part light guide structure part 2 is combined one
It rises and forms round cavity, the pumping laser leaked out from high-power optical fiber coupler cone can be 360 in the round cavity
Spend Homogeneouslly-radiating.Guide-lighting crystal block 3 is fitted closely with the D-shaped center inner groovy 4 on lower part light guide structure part 2 simultaneously, the leaded light
Crystal block 3 has highly thermally conductive property, high light transmission features and wide transmission region (note：Pumping laser wavelength is led in 900nm -1000nm
Luminescent crystal light transmitting wavelength：It is infrared in close) the advantages that, therefore the pumping laser of leakage can quickly be exported；Additionally due to guide-lighting
Crystal block 3 is designed as the semicolumn bodily form, can equally improve the heat dissipation uniformity of high-power optical fiber coupler cone.
