The device is simple to use, avoids repeatedly correction, the adjustment of visible light with the laser instrument, save time, reduction in production cost.
Description
Technical field
The utility model belongs to laser fiber-optic transmission technical field, particularly relates to the device of a kind of double light path adjustment laser and coupling fiber.
Background technology
Laser fiber-optic transmission technology is that the laser power that laser instrument exports is imported in optical fiber the technology making it transmit in a fiber.The efficiency that laser transmits in a fiber is mainly determined by the numerical aperture (NA) of optical fiber, fiber size and laser fiber couple state quality.After optical fiber is selected, couple state just becomes determinative.
The mode of existing laser instrument and coupling fiber is adjusted by single light path device.In single light path device, visible pilot light and laser coaxial are also through laser instrument.Reference pilot light when visible pilot light to be the auxiliary pilot light of laser instrument adjustment be also simultaneously laser and coupling fiber.Because thermal effect during laser works can cause visible pilot light to destroy the coaxial of visible pilot light and laser through producing refraction during laser instrument, repeatedly adjusting so need repeatedly to revise, laser could be continued and coupling fiber adjusts.Its process is very complicated, sometimes even can do again from the beginning.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of double light path to adjust the device of laser and coupling fiber, this device can judge that whether laser is coaxial with visible pilot light accurately, avoid the correction repeatedly to visible ray and laser instrument, adjustment, save time, reduce production cost.
For achieving the above object, the utility model adopts following technical scheme: the device of a kind of double light path adjustment laser instrument and coupling fiber, comprise the first illuminator, fiber coupling lens, coupling fiber adjustment rack, the second illuminator, Transflective mirror, described first illuminator is in the afterbody of laser instrument, the head of laser instrument sets gradually Transflective mirror, fiber coupling lens and coupling fiber adjustment rack, and the vertical direction of described Transflective mirror is provided with the second illuminator.
In technique scheme, between laser instrument and Transflective mirror, be provided with beam shaping.
The beneficial effects of the utility model are: device uses simple, avoid the correction repeatedly to visible ray and laser instrument, adjustment, save time, reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1. the first illuminator, 2. the first visible pilot light, 3. laser instrument, 4. laser, 5. beam shaping, 6. Transflective mirror, 7. the second illuminator, 8. the second visible pilot light, 9. fiber coupling lens, 10. coupling fiber adjustment rack, 11. optical fiber.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
A kind of double light path adjustment laser instrument as shown in Figure 1 and the device of coupling fiber, comprise the first illuminator 1, fiber coupling lens 9, coupling fiber adjustment rack 10, second illuminator 7, Transflective mirror 6, described first illuminator 1 is in the afterbody of laser instrument 3, the head of laser instrument 3 sets gradually Transflective mirror 6, fiber coupling lens 9 and coupling fiber adjustment rack 10, and the vertical direction of described Transflective mirror 6 is provided with the second illuminator 7.Device uses simple, avoids the correction repeatedly to visible ray and laser instrument, adjustment, saves time, reduce production cost.
In technique scheme, between laser instrument 3 and Transflective mirror 6, be provided with beam shaping 5.The laser beam adjustment that beam shaping 5 can send laser instrument 3, make the collimation of laser better, the hot spot that the laser like this after shaping is formed when being coupled is less, better effects if.
When using this to use novel device, be divided into following several step:
1, the power supply of the first illuminator 1 and the second illuminator 7 is connected, first illuminator 1 and the second illuminator 7 send the first instruction visible ray 2 and the second visible pilot light 8 respectively, first visible pilot light 2 reaches optical fiber 11 through laser instrument 3, beam shaping 5, Transflective mirror 6, fiber coupling lens 9, and the second visible pilot light 8 that the second illuminator 5 on vertical direction sends reaches optical fiber 11 through fiber coupling lens 9 after Transflective mirror 6 reflects.
2, the first illuminator and laser coaxial is adjusted.
3, adjust the second illuminator 7, make the second visible pilot light 8 coaxial with the first visible pilot light 2.
4, preliminary adjustment coupled lens 9 and coupling fiber adjustment rack 10, the angle making the first visible pilot light 2 and the second visible pilot light 8 enter optical fiber reaches standard state.
5, open laser instrument 3, and the laser 4 that laser instrument 3 sends is adjusted, make laser 4 coaxial with the second visible pilot light 8.
6, accurate adjustment is carried out to fiber coupling lens 9 and coupling fiber adjustment rack 10, the couple state of laser 5 and optical fiber 11 can be learnt from the second visible pilot light 8 at the light spot shape of optical fiber 11 output terminal.Under normal circumstances, laser coupling efficiency after coupling device reaches 92%, and the coupling efficiency of powerful laser instrument reaches 90%.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
