Abstract
The invention discloses a kind of Cladding Power Stripper, which includes stripping off device and optical fiber；Wherein, stripping off device is internally provided with a channel, and optical fiber is placed in the channel, and the cross section in the channel is V-arrangement.By the above-mentioned means, the present invention can be improved the quality of laser beam.
Description
Technical field
The present invention relates to field fibers, more particularly to a kind of Cladding Power Stripper.
Background technique
Doubly clad optical fiber is made of concentric fibre core, inner cladding, surrounding layer and protective layer, and inner cladding and surrounding layer have
Concentric circular structure, fibre core have very big refractive index as single mode optical fiber fibre core, are used to transmit single mode signal
Light；Inner cladding has material identical with the fibre core of ordinary optic fibre, its refractive index is between fibre core and surrounding layer, it is used to
Transmit multimode pump light；The refractive index of surrounding layer is minimum.Inner cladding and fibre core constitute a big fibre core, for transmitting pumping
Light is passed repeatedly through fibre core in a manner of broken line and is doped absorption, and the ratio that light is propagated in this way in fibre core just will increase.
It is basic using stripping in removing optical fiber when remaining pump light in existing fiber laser fabrication process technology
Except the protective layer and surrounding layer of optical fiber, then stretch optic fibre and in optical fiber applied atop high refractive index glue, makes remaining pump light
And the laser of the higher order mode filtered out gushes, and guarantees the safety of rear class device, while acting the work for improving quality for outputting laser beam
With.
But there are pump lights to strip not exclusively for aforesaid way, higher order mode laser gushes few problem, causes to export
Laser in two kinds of wavelength of doping light, and energy is not concentrated, i.e., beam quality is not good enough.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of Cladding Power Strippers, can be improved the matter of laser beam
Amount.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of Cladding Power Stripper is provided,
The Cladding Power Stripper includes stripping off device and optical fiber；The stripping off device is internally provided with a channel, the light
Fibre is placed in the channel, wherein the cross section in the channel is V-arrangement.
Wherein, the stripping off device is made of the good transparent glass material of thermal conductivity.
Wherein, the material is sapphire material.
Wherein, the stripping off device includes lower substrate and upper cover plate, and the V-type channel is arranged in the lower substrate.
Wherein, the V-arrangement channel is process by mechanical carving groove technology.
Wherein, the optical fiber is completely accommodated in the V-type channel.
Wherein, the inner surface in the V-type channel also coats binding material.
Wherein, part of the fiber containment in the channel, surrounding layer and protective layer are removed, only include fibre core and
Wrap up the inner cladding of the fibre core.
Wherein, the surface of the inner cladding is also covered with high refractive index material layer.
Wherein, the binding material of the surface coating high refractive index of the inner cladding.
The beneficial effects of the present invention are: being in contrast to the prior art, Cladding Power Stripper packet disclosed by the invention
Include stripping off device and optical fiber；Wherein, stripping off device be internally provided with a sliver transvers section be V-arrangement channel, optical fiber is placed in logical
In road.By the above-mentioned means, can effectively make outside the light-output optical fiber of the higher order mode in optical fiber in inner cladding, without influencing
Laser in fibre core is conducive to improve beam quality.
Detailed description of the invention
Fig. 1 is the overlooking structure diagram in one embodiment of Cladding Power Stripper of the present invention；
Fig. 2 is the schematic cross-sectional view in one embodiment of Cladding Power Stripper of the present invention；
Fig. 3 is the cross-sectional structure schematic diagram of the optical fiber in one embodiment of Cladding Power Stripper of the present invention.
Specific embodiment
Please refer to Fig. 1,2, the schematic diagram of the section structure of Cladding Power Stripper of the present invention, the Cladding Power Stripper
Including stripping off device 110 and optical fiber 120.Wherein, the stripping off device 110 be internally provided with a sliver transvers section be V-arrangement channel
111, optical fiber 120 is placed in channel 111.Specifically, as shown in Figure 2, optical fiber 120 is accommodated by channel 111 completely.
In the present embodiment, stripping off device 110 is made of the good transparent glass material of thermal conductivity, specifically, the material
Material is sapphire material, can also be made of the good material of other thermal conductivities.Wherein, setting should inside stripping off device 110
Channel 111, the channel 111 can be integrally formed with stripping off device 110, that is, chisel channel immediately above in processing
111。
As shown in figure 3, optical fiber 120 is doubly clad optical fiber comprising concentric fibre core 121, inner cladding 122, surrounding layer 123
And protective layer 124.Before optical fiber 120 is put into channel 111, need to remove the part fiber 120 being contained in channel 111
Protective layer 124 and surrounding layer 123, make inner cladding 122 directly it is exposed.
Further, when optical fiber 120 being put into the channel 111, the part light of protective layer 124 and surrounding layer 123 is removed
Fibre is contained in the channel 111, and coats binding material on exposed 122 surface of inner cladding, and optical fiber 120 is made to be fixed on channel
In 111.Wherein, which is ultraviolet glue.
In implementation process, optical path enters from side, there is laser and pump light, and pump light is propagated in inner cladding 122, by
In eliminating protective layer 124, and the refractive index of the ultraviolet glue of surface coating is greater than the refractive index of surrounding layer 123, and pump light is just not
It can be totally reflected on covering, and can be from being exported in covering outside optical fiber 120, and be placed in V-shaped groove because of optical fiber 120, the V-arrangement
Slot is formed in stripping off device 110 made of sapphire material, so gushing pump light meeting in the sapphire slot for encountering V-arrangement
It is propagated by waveguide of sapphire, rushing down light effect can be more complete.
It is different from the prior art, the Cladding Power Stripper of present embodiment includes stripping off device and optical fiber；Wherein, it removes
Device is internally provided with the channel that a sliver transvers section is V-arrangement, and optical fiber is placed in channel.By the above-mentioned means, can be effective
The light-output optical fiber for making the higher order mode in optical fiber in inner cladding outside, without influence fibre core in laser, be conducive to improve light
Beam quality.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
