To carry Large Copacity information.The axis of the light beam of the most existing current Laser Devices laser and the axis of ceramic insertion core
Overlapping, enter laser diode to reduce reflection light, improve the stability of laser instrument, laser instrument is necessarily required to first pass through one
Individual have APC end face (end face of ceramic insertion core be plane be referred to as PC face, the end face at the certain angle of inclination of end face band is referred to as APC
Face) ceramic insertion core A, then be connected to the PC face of the ceramic insertion core B of light wire jumper by another PC end face of ceramic insertion core A
Complete adaptation.
The structure of above-mentioned laser instrument needs the ceramic insertion core of one section of APC-PC to carry out adaptation, thus add the cost of raw material and
The process costs of assembling, and can substantially increase the length of light receiving element, it is unfavorable for the miniaturization of optical device.Additionally, on the market
Also having some transmitting optical device products without ceramic insertion core, this product does not solve light reflection problems, and laser characteristics can not
It is guaranteed.
Summary of the invention
It is an object of the invention to solve the problems referred to above and propose a kind of Laser Devices, these Laser Devices have at guarantee laser instrument special
The advantage reducing laser instrument manufacturing cost on the premise of property.
To achieve these goals, the technical scheme that the present invention takes is as follows:
The present invention proposes a kind of Laser Devices, and including laser diode, lens, ceramic insertion core and optical fiber, described lens are located at sharp
Between optical diode and ceramic insertion core, the axis of described ceramic insertion core is one with the axis of described laser diode institute isolychn
Angle Q, the axis of described laser diode institute isolychn is arranged with described vertical lens, described laser diode issued light
Line enters into ceramic insertion core by the focusing of lens, and described optical fiber is connected with ceramic insertion core.
Further, the end face B of described ceramic insertion core is PC plane.
Preferably, described ceramic insertion core is the ceramic insertion core of light wire jumper.
Preferably, described angle Q is 2 °-10 °.
Preferably, also include that porcelain bushing, described porcelain bushing are placed on the fore-end of ceramic insertion core.
Beneficial effects of the present invention:
1. compared with traditional Laser Devices, The present invention reduces one section of ceramic insertion core, such that it is able to bigger reduction raw material becomes
Basis and assembly cost；
2. compared with traditional Laser Devices, The present invention reduces one section of ceramic insertion core, so that the size of Laser Devices is permissible
Less, it is more beneficial for the miniaturization of Laser Devices；
3. axis and the lens of the laser diode issued light line of the present invention are mutually perpendicular to, then just can directly use industry
The packing forms of the laser diode of standard substance, it is easier to the production in enormous quantities of this optical device.

Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, attached below in conjunction with in the embodiment of the present invention
Figure, is clearly and completely described the technical scheme in the embodiment of the present invention, it is clear that described embodiment is the present invention
A part of embodiment rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not having
Make the every other embodiment obtained under creative work premise, broadly fall into the scope of protection of the invention.
It is illustrated in figure 1 the structural representation of existing Laser Devices on market, enters laser due to reflection in order to reduce light
Diode, causes the instability of laser instrument.Single-mode laser be necessarily required to first pass through one have APC end face (as in figure 2 it is shown,
The end face of ceramic insertion core be plane be referred to as PC face, the end face at the certain angle of inclination of end face band is referred to as APC face) ceramic insertion core A,
The PC face of the ceramic insertion core B being connected to light wire jumper by another PC end face of ceramic insertion core A again completes adaptation.?
Can reach to reduce reflection light and enter the purpose of laser diode.The structure of above-mentioned laser instrument needs the pottery of one section of APC-PC to insert
Core carries out adaptation, thus adds the process costs of the cost of raw material and assembling, and can substantially increase the length of light receiving element,
It is unfavorable for the miniaturization of optical device.
Based on drawbacks described above, the present invention proposes a kind of Laser Devices, as it is shown on figure 3, include laser diode, lens, pottery
Lock pin and optical fiber, this ceramic insertion core is the ceramic insertion core of light wire jumper.Described lens are located between laser diode and ceramic insertion core,
The axis of described ceramic insertion core and the axis Q at an angle of described laser diode institute isolychn, described laser diode institute
The axis of isolychn is arranged with described vertical lens, and described laser diode issued light line enters into pottery by the focusing of lens
Porcelain lock pin, described optical fiber is connected with ceramic insertion core, and reflection light is reflected at angle Q that the axis of ceramic insertion core becomes with it
And do not enter in laser diode, decrease reflection light and enter the purpose of laser diode, thus serve and overcome reflection
Effect.The Laser Devices of the present invention decrease one section of ceramic insertion core, the reduction cost of raw material that one side can be bigger in composition
And assembly cost, on the other hand so that the size of Laser Devices can be less, it is more beneficial for the miniaturization of Laser Devices.This
Outward, axis and the lens of the laser diode issued light line of the present invention are mutually perpendicular to, then just can directly use industry mark
The packing forms of the laser diode of quasi-product, it is easier to the production in enormous quantities of this optical device.
As a kind of preferred version, ferrule endface B used by the present invention is PC plane, and the axis of ceramic insertion core is with described
The axis Q at an angle of laser diode institute isolychn, this angle Q is 2 °-10 °, meanwhile, in order to strengthen laser two pole
The stability of pipe institute isolychn, present invention additionally comprises porcelain bushing, and porcelain bushing is placed on the fore-end of ceramic insertion core.
