Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Based on this, the present invention provides a discrete polarization laser beam splitting device, as shown in fig. 1 and fig. 2, the device includes: a first optical rotation component 20-1, a first polarization beam splitting component 30-1 and a first total reflection component. The first optical rotation assembly 20-1 is used for changing the vibration direction of the polarized laser light 10, and the first polarization beam splitting assembly 30-1 is used for splitting the polarized laser light 10 into vertically polarized laser light and horizontally polarized laser light. The first total reflection assembly is used for reflecting the horizontal polarization laser to adjust the propagation path of the horizontal polarization laser, so that the horizontal polarization laser and the vertical polarization laser form two beams of emergent laser. The first optical rotation component 20-1, the first polarization light splitting component 30-1 and the first total reflection component are sequentially arranged.
The first optically active member 20-1 is used to change the vibration direction of the polarized laser light 10, and the type, shape and number of the first optically active member 20-1 are not limited in this case, for example, the first optically active member 20-1 may be a wave plate or a faraday rotator, and the wave plate may be a quarter wave plate, a half wave plate or an eighth wave plate. The first optical rotation assembly 20-1 is used for rotating the vibration direction of the polarized laser light 10 to change the energy of the two laser beams formed after the polarized laser light 10 is split. Meanwhile, the first optically active member 20-1 is used to change the vibration direction of the polarized laser light 10 so that the polarized laser light 10 of any vibration direction can be split into two laser lights by the first polarization beam splitting assembly 30-1, for example, if the polarization angle of the polarized laser light 10 is horizontal or vertical, i.e., the polarized laser light 10 entering the first polarization beam splitting assembly 30-1 is a horizontally polarized laser light or a vertically polarized laser light, it cannot be split into two laser lights, but the first optically active member 20-1 is selected appropriately, and after the laser light passes through the first optically active member 20-1, the polarized laser light 10 of any vibration direction can be split.
The first polarization beam splitting assembly 30-1 is configured to split the polarized laser light 10 into a vertically polarized laser light and a horizontally polarized laser light, wherein vibration directions of the vertically polarized laser light and the horizontally polarized laser light are perpendicular to each other. The type and shape of the first polarization beam splitting assembly 30-1 are not limited in particular, and the first polarization beam splitting assembly 30-1 may be a polarization beam splitting prism or a polarizer, and the prism may be a tetrahedron, an octahedron or other shapes.
The first total reflection assembly is used for reflecting the horizontal polarization laser to adjust the propagation path of the horizontal polarization laser, so that the horizontal polarization laser and the vertical polarization laser form two beams of emergent laser. The type and number of the first total reflection assemblies are not particularly limited, and the first total reflection assemblies are used for changing the light path direction of the horizontal polarized laser, namely the propagation path of the horizontal polarized laser, so that the horizontal polarized laser and the vertical polarized laser emit two beams of emergent laser from the discrete polarized laser beam splitting device.
The first optical rotation component 20-1, the first polarization light splitting component 30-1 and the first total reflection component are sequentially arranged, that is, the polarized laser firstly passes through the first optical rotation component 20-1 and then reaches the first polarization light splitting component 30-1, the first polarization light splitting component 30-1 splits the polarized laser into two beams of laser, wherein the horizontally polarized laser enters the first total reflection component.
Therefore, the first optical rotation component 20-1 changes the vibration direction of the polarized laser to distribute the energy of the emitted laser, the first polarization beam splitting component 30-1 splits the polarized laser into two beams of emitted laser, and the first total reflection component changes the propagation path of the horizontally polarized laser to adjust the distance and the included angle between the emitted laser. Therefore, by adopting the discrete polarized laser beam splitting device provided by the invention, two beams of emergent laser can be obtained by only one laser emitter, and the energy, polarization, included angle, interval and other optical parameters of the emergent laser can be adjusted.
In other embodiments, as shown in FIG. 1, the first polarization beam splitting component 30-1 includes a first surface 30-1-1 and a second surface 30-1-2, the first surface 30-1-1 is adjacent to the first optically active component 20-1, and the second surface 30-1-2 is adjacent to the first totally reflecting component. The first surface 30-1-1 is sequentially provided with a high-reflection film for reflecting the vertically polarized laser and a first high-transmission film for transmitting the horizontally polarized laser, and the second surface 30-1-2 is provided with a second high-transmission film. Namely, the high-reflection film is a high-reflection film of vertically polarized laser (s light), and is referred to as the s light high-reflection film for short. The first high-transmission film and the second high-transmission film are high-transmission films for horizontally polarized laser (p light), and are referred to as p light high-transmission films for short. The s-light high-reflection film and the p-light high-transmission film ensure that horizontal polarized laser in the polarized laser can fully pass through the first polarization light splitting component 30-1 and the first polarization light splitting component 30-1 to fully reflect vertical polarized laser, and ensure that the vibration directions of the two beams of emergent laser are mutually vertical. Some types of first polarization splitting assemblies 30-1 include a polarizer, which is in the shape of a rectangular parallelepiped as shown in fig. 1, 2, and 3. As shown in fig. 4, another first polarization splitting assembly 30-1 further includes a polarization splitting prism having a cube shape, and the s-light high-reflection film and the p-light high-transmission film are sequentially disposed on a diagonal surface of the cube-shaped polarization splitting prism, and the polarized laser light is split at the diagonal surface to form vertically polarized laser light and horizontally polarized laser light.
In other embodiments, as shown in fig. 1 and 2, the first surface 30-1-1 reflects the vertically polarized laser light of the polarized laser light 10 to form a first emitted laser light 10-1. The first surface 30-1-1 is provided with the s-light high-reflection film and the p-light high-transmission film, so that horizontal polarized laser light in the polarized laser light can fully pass through the first polarization light splitting component 30-1 and can fully reflect vertical polarized laser light to form first emitted laser light 10-1.
In other embodiments, as shown in fig. 1 and 2, the first total reflection assembly includes: the laser device comprises a first total reflector 40-1 and a second total reflector 50-1, wherein the first total reflector 40-1 reflects the horizontally polarized laser to the second total reflector 50-1, and the second total reflector 50-1 reflects the horizontally polarized laser to the first polarization light splitting component 30-1 and emits the horizontally polarized laser from the first surface 30-1-1 to form a second emitted laser 10-2. The first total reflector 40-1 and the second total reflector 50-1 can be adopted to conveniently adjust the propagation path of the horizontally polarized laser, and the adjustment mode is stable and simple.
In other embodiments, the position of the first total reflecting mirror 40-1 and the position of the second total reflecting mirror 50-1 can both be moved relative to the first polarization beam splitting assembly 30-1 to adjust the distance between the horizontally polarized laser light and the vertically polarized laser light when they are emitted from the first surface 30-1-1, i.e. adjust the distance between the first emitted laser light 10-1 and the second emitted laser light 10-2 when they are emitted from the first surface 30-1-1. It is apparent that two laser beams (the first outgoing laser beam 10-1 and the second outgoing laser beam 10-2) at an arbitrary interval can be obtained by adjusting the position of the first total reflecting mirror 40-1 and the position of the second total reflecting mirror 50-1, for example, the interval of the optical axes of the two outgoing laser beams (the first outgoing laser beam 10-1 and the second outgoing laser beam 10-2) may be 2mm, 5mm, 10mm, or other distances. This adjustment is particularly suitable for dividing the polarized laser into two compact beams of laser light in a limited space, for example, when the two beams of laser light are overlapped by a part of light spots on the ground, the two beams of laser light are visible as one beam of laser light (actually two beams of laser light), but can be gradually separated into two beams of laser light at a height of 100km, and can excite two sodium atoms to generate two sodium guide stars.
In some other embodiments, the first total reflecting mirror 40-1 and the second total reflecting mirror 50-1 are capable of rotating to rotate the first total reflecting mirror 40-1 and the second total reflecting mirror 50-1 to adjust an included angle between the horizontally polarized laser light and the vertically polarized laser light emitted from the first surface 30-1-1, that is, an included angle between the first emitted laser light 10-1 and the second emitted laser light 10-2 emitted from the first surface 30-1-1. It is obvious that two beams of outgoing laser (the first outgoing laser 10-1 and the second outgoing laser 10-2) which are parallel or have a certain included angle can be obtained by rotating the first total reflecting mirror 40-1 and the second total reflecting mirror 50-1, and the included angle can be arbitrarily adjusted, for example, 1.5 ° or 1 ° or the like, and the adjustment mode is suitable for dividing the polarized laser into two beams of outgoing laser with arbitrary angles in a limited space.
In other embodiments, the first optically active assembly 20-1 comprises: a half-wave plate. The half-wave plate can be adopted to ensure that the energy distribution of the obtained emitted laser is more uniform. Especially, when a plurality of discrete polarized laser beam splitting devices are used in a matched mode, the half-wave plate can rotate laser emitted horizontally or vertically to generate a plurality of laser beams with uniform energy distribution.
In some other embodiments, the apparatus further comprises a laser 00, said laser 00 being adapted to generate said polarized laser light 10.
In other embodiments, the laser 00 is used to generate linearly polarized laser light 10, circularly polarized laser light 10, or elliptically polarized laser light 10.
According to another aspect of the present invention, based on the foregoing embodiments, there is further provided a discrete polarized laser beam splitting system, including the discrete polarized laser beam splitting device provided in any of the foregoing embodiments, where the discrete polarized laser beam splitting system includes n discrete polarized laser beam splitting devices sequentially arranged to split the polarized laser beam 10 into 2nAnd (5) beam laser. As shown in fig. 3, when n is 2, the second optical rotation element 20-2, the second polarization beam splitter element 30-2, and the second total reflection element are sequentially disposed along the optical path direction of the first outgoing laser light 10-1 and the second outgoing laser light 10-2, and a certain included angle exists between the second polarization beam splitter element 30-2 and the second optical rotation element 20-2. The first outgoing laser 10-1 passes through the second optical rotation component 20-2, the second polarization beam splitting component 30-2, the third total reflection mirror 40-2 and the fourth total reflection mirror 50-2 to form two outgoing laser 10-1-1 and 10-1-2, the second outgoing laser 10-2 passes through the second optical rotation component 20-2, the second polarization beam splitting component 30-2, the third total reflection mirror 40-2 and the fourth total reflection mirror 50-2 to form two laser 10-2-1 and 10-2-2, and 2 is formed in total2Beam laser, i.e. 4 beams laser. Similarly, when the number of the discrete polarization laser beam splitting devices is n, 2 can be formednAnd (5) beam laser. This adjustment is particularly suitable for dividing the polarized laser light into n compact beams of laser light in a limited space, for example, when the laser light is on the ground, the n beams of laser light are visible as one beam of laser light (actually n beams of laser light) due to the superposition of partial light spots, but can be gradually divided into n beams of laser light at a height of 100km, and n sodium atoms can be excited to generate n sodium guide stars to form a star group.
