All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, an embodiment of the present invention provides a dual magneto-optical trap divergent laser alignment adjustment system, including:
the single-beam laser alignment structure comprises a first auxiliary alignment structure and eight single-beam laser assemblies 3, wherein the first auxiliary alignment structure is used for aligning the axis of divergent laser emitted in each single-beam laser assembly 3 with the normal of a reference reflector 2 corresponding to the divergent laser; the method comprises the steps of,

Specifically, in this embodiment, in the single-beam laser alignment structure, the axis of the divergent laser emitted in each single-beam laser component 3 is aligned with the normal line of the reference mirror 2 corresponding to the divergent laser through the first auxiliary alignment structure, then eight single-beam laser components 3 are transferred to the eight-beam laser alignment structure, and then the normal lines of the reference mirrors 2 corresponding to the eight-beam divergent lasers one by one and orthogonal to each other are aligned with the axis of the second internal focusing telescope 8 in the second auxiliary alignment structure through the second auxiliary alignment structure, so as to implement the orthogonal alignment of the eight-beam divergent lasers.
Therefore, the invention leads out the optical axis direction of the divergent laser to the normal line of the reference reflector, and then carries out precise alignment adjustment on the normal line direction of the reference reflector, in particular to adjust the normal line of the reference reflector which is mutually orthogonal in eight single-beam laser components to be parallel to the axis of the second internal focusing telescope, thus completing the orthogonal adjustment of the normal line direction of the eight reference reflectors, which is equivalent to realizing the orthogonal alignment of the eight laser beams, and further meeting the use requirement of the atomic gyro engineering prototype.
Optionally, the first auxiliary alignment structure includes two first inner focusing telescopes 7 disposed opposite to each other, and axes between the two first inner focusing telescopes 7 are aligned.
Optionally, in the single-beam laser alignment structure, the single-beam laser assembly 3 includes an optical fiber head 1 and a reference reflector 2 disposed between two first internal focusing telescopes 7, and the reference reflector 2 is connected to the back of a laser emission port of the optical fiber head 1;
wherein, the axis of the divergent laser emitted by the optical fiber head 1 is parallel to the axis of one of the first internal focusing telescope 7, and the normal line of the reference reflector 2 is parallel to the axis of the other first internal focusing telescope 7.
Referring to fig. 1, two first inner focusing telescopes 7 are oppositely placed, and meanwhile, the axes between the two first inner focusing telescopes 7 are aligned, one single-beam laser component 3 is placed on the two first inner focusing telescopes 7, the axes of divergent laser emitted by the optical fiber head 1 are parallel to the axes of one first inner focusing telescope 7 by adjusting the postures of the single-beam laser component 3, and then the postures of the reference reflector 2 are independently adjusted, so that the normal line of the reference reflector 2 is parallel to the axes of the other first inner focusing telescope 7, and the fact that the axes of divergent laser emitted by the optical fiber head 1 are parallel to the normal line direction of the reference reflector 2 is guaranteed.
Thus, according to the same operation method as described above, the axis of the divergent laser light emitted from the optical fiber head 1 of each single-beam laser module 3 (eight in total) is parallel to the normal direction of the reference mirror 2.
Optionally, the second auxiliary alignment structure includes a turntable 6, a frame 4 disposed on the turntable 6, a directional mirror 5 disposed on a side of the frame 4, and a second internal focusing telescope 8 disposed on a side of the directional mirror 5, wherein an axis of the second internal focusing telescope 8 is aligned with a normal line of the directional mirror 5.
Optionally, in the eight-beam laser alignment structure, eight single-beam laser assemblies 3 are all movably connected to the frame 4, wherein four single-beam laser assemblies 3 form a first laser group and are arranged on one side of the frame 4, another four single-beam laser assemblies 3 form a second laser group and are arranged on the other opposite side of the frame 4, and each single-beam laser assembly 3 in the first laser group and each single-beam laser assembly 3 in the second laser group are symmetrically distributed;
wherein, the axes of the divergent laser light emitted by two adjacent single-beam laser components 3 in the first laser group near the directional reflector 5 are respectively arranged at 45 degrees with the normal line of the directional reflector 5, and the axes of the divergent laser light emitted by the other two single-beam laser components 3 in the first laser group are respectively arranged orthogonal with the axes of the divergent laser light emitted by two single-beam laser components 3.
Alternatively, in the eight-beam laser alignment structure, the optical fiber head 1 in each single-beam laser assembly 3 is disposed inward, and the reference mirror 2 in each single-beam laser assembly 3 is disposed outward.
It will also be appreciated that in an eight beam laser alignment configuration, the fibre optic head 1 in each single beam laser assembly 3 is located close to the centre of the turret 6 and the reference mirror 2 in each single beam laser assembly 3 is located away from the centre of the turret 6.
Optionally, in the eight-beam laser alignment structure, the optical fiber head 1 in each single-beam laser assembly 3 is fixedly connected with the corresponding reference mirror 2.
Referring to fig. 2 specifically, after the axes of the divergent lasers emitted from the fiber heads 1 of the eight single-beam laser assemblies 3 are aligned parallel to the normal direction of the reference mirror 2, the fiber heads 1 in each single-beam laser assembly 3 need to be fixedly connected to the corresponding reference mirror 2, and then the eight single-beam laser assemblies 3 are mounted on the frame 4, and the eight single-beam laser assemblies 3 are arranged in the following manner:
the four single-beam laser components 3 form a first laser group and are arranged on one side edge of the frame 4, the other four single-beam laser components 3 form a second laser group and are arranged on the other opposite side edge of the frame 4, and each single-beam laser component 3 in the first laser group and each single-beam laser component 3 in the second laser group are symmetrically distributed;
wherein, two adjacent single-beam laser components 3 in the first laser group close to the directional reflector 5 are respectively arranged at 45 degrees with the directional reflector 5, and the other two single-beam laser components 3 in the first laser group are arranged orthogonally with two single-beam laser components 3.
However, in the above-mentioned installation and arrangement process of the eight single-beam laser assemblies 3, the manual operation is performed, so that an installation error inevitably exists, and it cannot be ensured that all the eight single-beam laser assemblies 3 can be orthogonally arranged without error, and that the eight scattered lasers cannot be orthogonally aligned. Therefore, for this problem, the precise turntable 6 and the second internal focusing telescope 8 are required to precisely adjust the normal directions of the eight reference mirrors 2 to achieve orthogonal adjustment of the eight scattered lasers.
For convenience of explanation of the adjustment process of the eight single-beam laser assemblies 3, the grouping of the eight single-beam laser assemblies 3 is defined as follows:
two adjacent single-beam laser components 3 of the first laser group, which are close to the directional reflector 5, form a first group and are arranged along the upper right side of the frame 4;
the other two single-beam laser assemblies 3 in the first laser group constitute a second group (upper left in fig. 2);
two adjacent single-beam laser assemblies 3 of the second laser group, which are close to the directional mirror 5, form a third group (lower right in fig. 2);
the other two single-beam laser assemblies 3 in the second laser group constitute a fourth group (lower left in fig. 2).
Since the turntable 6 is a circular member, there is a division of clockwise rotation and counterclockwise rotation during rotation, and the specific operation steps are as follows:
it should be noted that, during the adjustment of the normal line of the reference mirror 2, the single-beam laser assembly 3 including the reference mirror 2 is integrally adjusted, because the reference mirror 2 is fixedly connected with the optical fiber head 1, and during the early adjustment of the single-beam laser alignment structure, the divergent laser beam of the optical fiber head 1 is aligned with the reference mirror 2, and during the adjustment of the eight-beam laser alignment structure, a certain part of the single-beam laser assembly 3 cannot be individually adjusted, so that the overall posture of the single-beam laser assembly 3 needs to be adjusted.
1. Clockwise:
step one, when the turntable 6 rotates 45 degrees clockwise, adjusting to align the normals of the two reference reflectors 2 in the first group with the axis of the second internal focusing telescope 8;
step two, when the turntable 6 rotates 90 degrees clockwise again, adjusting to align the normals of the two reference reflectors 2 in the second group with the axis of the second internal focusing telescope 8;
step three, when the turntable 6 is rotated clockwise by 90 degrees again, adjusting to align the normals of the two reference reflectors 2 in the fourth group with the axis of the second internal focusing telescope 8;
step four, when the turret 6 is rotated again by 90 degrees clockwise, the normals of both reference mirrors 2 in the third group are adjusted to be aligned with the axis of the second in-focus telescope 8.
2. Counterclockwise:
step one, when the turntable 6 rotates 45 degrees anticlockwise, adjusting to align the normals of the two reference reflectors 2 in the third group with the axis of the second internal focusing telescope 8;
step two, when the turntable 6 rotates 90 degrees anticlockwise again, adjusting to align the normals of the two reference reflectors 2 in the fourth group with the axis of the second internal focusing telescope 8;
step three, when the turntable 6 is rotated 90 degrees counterclockwise again, adjusting to align the normals of the two reference mirrors 2 in the second group with the axis of the second internal focusing telescope 8;
step four, when the turret 6 is rotated counterclockwise by 90 degrees again, the adjustment is made so that the normals of both reference mirrors 2 in the first group are aligned with the axis of the second in-focus telescope 8.
Therefore, the invention establishes an external reference for the optical axis of the scattered laser through the reference reflector, leads the optical axis direction of the scattered laser to the normal line of the reference reflector, and carries out precise adjustment for the normal line direction of the reference reflector through the precise turntable and the second internal focusing telescope so as to realize orthogonal adjustment for eight beams of scattered laser.
