All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides an optical path adjusting structure, as shown in fig. 1, the optical path adjusting structure includes: an optical path adjusting component 2, a plurality of optical fiber launching components 1 and a plurality of optical fiber output components 3. The optical fiber emitting assemblies 1 are sequentially arranged, the position of the optical path adjusting assembly 2 is adjustable, and the optical path adjusting assembly 2 is positioned in an optical path between all the optical fiber emitting assemblies 1 and one of the optical fiber output assemblies 3, or the optical path adjusting assembly 2 is adjusted to be outside the whole optical path, so that when the optical path adjusting assembly 2 is moved, the optical path adjusting assembly 2 simultaneously combines and outputs laser emitted by all the optical fiber emitting assemblies 1 in different optical fiber output assemblies 3.
It will be appreciated that the number of fibre launch assemblies 1 can be freely adjusted according to the actual requirements. In this embodiment, the number of the optical fiber launching assemblies 1 is three, and the three optical fiber launching assemblies are respectively a first optical fiber launching assembly, a second optical fiber launching assembly and a third optical fiber launching assembly which are sequentially arranged. The number of the optical fiber output assemblies is two, and the optical fiber output assemblies are respectively a first optical fiber output assembly and a second optical fiber output assembly. The first optical fiber output assembly and the second optical fiber output assembly output different light spot sizes and output apertures (NA) respectively. The incident end of the first optical fiber output assembly is simultaneously aligned with each optical fiber launching assembly 1, that is, the incident end of the first optical fiber output assembly is simultaneously and directly aligned with the first optical fiber launching assembly, the second optical fiber launching assembly and the third optical fiber launching assembly. The incident end of the second optical fiber output assembly is aligned with each optical fiber launching assembly 1 through the optical path adjusting assembly 2, namely the incident end of the second optical fiber output assembly is aligned with the first optical fiber launching assembly, the second optical fiber launching assembly and the third optical fiber launching assembly through the optical path adjusting assembly 2.
When the optical path adjusting component 2 moves to the outside of the whole optical path, the laser output by the first optical fiber emitting component, the second optical fiber emitting component and the third optical fiber emitting component is directly injected into the first optical fiber output component, and beam combination and output are completed in the first optical fiber output component. When the optical path adjusting component 2 is adjusted to the optical path between the optical fiber transmitting component 1 and the second optical fiber output component, the laser output by the first optical fiber transmitting component, the second optical fiber transmitting component and the third optical fiber transmitting component is emitted into the second optical fiber output component through the optical path adjusting component 2, and beam combination and output are completed in the second optical fiber output component. Because the first optical fiber output assembly and the second optical fiber output assembly respectively output different light spot sizes and output apertures, the output spatial beam combining light can be guided into output ends with different core diameter sizes, and the output light spot sizes and the output apertures can be adjusted.
It should be noted that, when adjusting the optical path adjusting component 2, the optical path adjusting component 2 may not be moved outside the whole optical path, but the exit end of the optical path adjusting component 2 is adjusted, so that the exit end of the optical path adjusting component 2 can correspond to different optical fiber output components in the moving process. Especially, when more than two optical fiber output assemblies 3 are arranged, assuming that the number of the optical fiber output assemblies 3 is N, the optical path adjusting assembly 2 can only complete the combined output of one optical fiber output assembly 3 at most when moving to the outside of the whole optical path. The optical path adjusting component 2 needs to be capable of corresponding to at least N-1 optical fiber output components 3 when adjusting in the optical path.
According to the optical path adjusting structure and the optical path adjusting system, the optical path adjusting component is arranged in the optical path between all the optical fiber transmitting components and one of the optical fiber output components or is adjusted to be outside the whole optical path through the optical path adjusting component with the adjustable position, so that when the optical path adjusting component is moved, the optical path adjusting component simultaneously combines and outputs the laser emitted by all the optical fiber transmitting components in different optical fiber output components. The optical fiber output assembly can be adjusted according to the requirements of users, the adjustment of the size of an output light spot and the output aperture is realized, the time and the cost for repeatedly manufacturing the pumping source module are avoided, and the use space of the pumping source in the whole laser is reduced.

Each fiber output assembly 3 comprises: a collimator lens 31 and an output optical fiber 32 arranged in this order in the optical path direction. The sizes of the output fibers 32 in the fiber output assemblies 3 are different from each other to realize the adjustment of the output light spot size and the output aperture. Each of the fiber launch assemblies 1 further comprises: a first mirror 13. The laser chips 11 in each optical fiber emitting component 1 are arranged in a ladder shape in sequence, and the first reflecting mirror 13 is installed in the light path between the corresponding slow axis collimating lens 14 and the light path adjusting component 2. In the present embodiment, the optical path can be rotated by 90 ° by the first reflecting mirror 13
The optical path adjusting member 2 includes: a second reflecting mirror 21 and a third reflecting mirror 22 arranged in this order along the optical path. When the optical path adjusting assembly 2 is located in the optical path between all the fiber emission assemblies 1 and one of the fiber output assemblies 3, the incident end of the second reflector 21 is aligned with the corresponding first reflector 13, and the exit end of the third reflector 22 is aligned with the corresponding collimating lens 31.
When the optical path adjusting assembly 2 moves to the outside of the whole optical path, the laser emitted from each laser chip 11 is directly emitted into the first optical fiber output assembly through the corresponding fast axis collimating lens 12 and the first reflector 13, a spatial beam combination is formed in the collimating lens 31 of the first optical fiber output assembly, and finally the laser is input into the output optical fiber 32 of the first optical fiber output assembly.
When the optical path adjusting component 2 is adjusted to the optical path between the optical fiber emitting component 1 and the second optical fiber output component, the laser emitted by each laser chip 11 is emitted into the optical path adjusting component 2 through the corresponding fast axis collimating lens 12 and the first reflecting mirror 13, the laser direction is adjusted under the action of the second reflecting mirror 21 and the third reflecting mirror 22 in the optical path adjusting component 2, and the laser is emitted into the second optical fiber output component, a spatial beam is formed in the collimating lens 31 of the second optical fiber output component, and finally the laser is input into the output optical fiber 32 of the second optical fiber output component.
The optical path adjusting assembly may be additionally provided with a lens frame in which the second reflecting mirror 21 and the third reflecting mirror 22 are installed, and manually adjusted by an operator in a working environment, or controlled using a position adjusting mechanism. The position of the optical path adjusting component 2 is adjusted by using the position adjusting mechanism, so that the optical path adjusting component 2 is positioned in the optical path between all the optical fiber emitting components 1 and one of the optical fiber output components 3, or the optical fiber emitting component 1 is positioned outside the whole optical path, and the optical path adjusting component 2 simultaneously combines and outputs the laser emitted by all the optical fiber emitting components 1 in different optical fiber output components 3.

The structure of the optical path adjusting structure can refer to the above embodiments, and is not described herein again. The control mechanism is electrically connected with the optical path adjusting component 2 and each optical fiber emitting component 1, and is used for controlling the optical path adjusting component 2 to simultaneously combine and output the laser emitted by each optical fiber emitting component 1 in different optical fiber output components 3.

The incident end of the first fiber output assembly is simultaneously directly aligned with the first fiber launch assembly, the second fiber launch assembly and the third fiber launch assembly. The incident end of the second optical fiber output component is aligned with the first optical fiber emission component, the second optical fiber emission component and the third optical fiber emission component through the optical path adjusting component 2.
When the control mechanism controls the optical path adjusting component 2 to move outside the whole optical path, the control mechanism controls the lasers output by the first optical fiber transmitting component, the second optical fiber transmitting component and the third optical fiber transmitting component to directly inject into the first optical fiber output component, and beam combination and output are completed in the first optical fiber output component. When the control mechanism controls the light path adjusting component 2 to adjust the light path between the optical fiber emitting component 1 and the second optical fiber output component, the control mechanism controls the laser output by the first optical fiber emitting component, the second optical fiber emitting component and the third optical fiber emitting component to be emitted into the second optical fiber output component through the light path adjusting component 2, and beam combination and output are completed in the second optical fiber output component.
