TECHNICAL FIELD

[0002] Laser has been widely used in many fields due to its high brightness, good coherence, strong directivity and other advantages. Different fields have different requirements for laser, and therefore the editing of laser beam plays an irreplaceable role in the application of laser.

[0003] Light beam spatial domain editing refers to changing the distribution of laser energy in the spatial range, which has important applications in the fields of laser processing, laser communication, laser display, etc. Commonly used spatial domain editing is mostly based on refraction or reflection principle, which divides and recombines the wavefront of the light beam by using the refraction or reflection principle of the light beam. This method usually has serious defects such as complex experimental system, low energy utilization rate and poor editing precision. Thereafter, methods such as fiber editing, aspheric lens editing, microlens array editing and diffractive optical element editing appeared, but these methods have the disadvantages of high requirements for experimental devices, complex device manufacturing and large energy loss. Although the method of light beam spatial domain editing has been developed, if different components in the light beam are to be edited, the existing methods all need to divide the light beam into multiple beams, edit them respectively and then combine them, which undoubtedly increases the instability of the system and also increases the complexity of the system. At the same time, the combining process is extremely susceptible to the environment, which leads to a decrease in the precision of the combining process and even failure of the combining process.

[0004] Therefore, how to solve the problems of high requirements for editing devices, large energy loss and the need for splitting and combining in the editing of multiple components in the existing light beam spatial domain editing is a technical problem that needs to be solved by people in the field.

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0035] The core of the present application is to provide a light beam spatial domain editing device, system, method, equipment and medium, which is used to solve the problems of high requirement for editing device, large energy loss and the need for beam splitting and combining in multi-component editing in the existing light beam spatial domain editing.

[0036] In order to enable those skilled in the art to better understand the present application, the present application will be further described in detail in combination with the drawings and specific embodiments. Figure 1 A schematic diagram of a light beam spatial domain editing device provided by an embodiment of the present application is shown in FIG. 1. Figure 1As shown, it comprises: a spatial editor 3, a 4f optical system 2 comprising a polarizer P;

[0037] The 4f optical system 2 and the spatial editor 3 are sequentially located in the transmission direction of the light beam emitted by the light source;

[0038] The first grating G1 in the 4f optical system 2 is used to convert the same light beam emitted by the light source 1 from the time domain to the frequency domain to realize the spatial separation of different wavelengths of light in the same light beam;

[0039] The polarizer P is located between the Fourier plane between the first lens L1 and the second lens L2 of the 4f optical system 2 and in the transmission direction of the light to be edited in the same light beam, and is used to change the polarization direction of the light to be edited;

[0040] The second grating G2 in the 4f optical system 2 is used to combine the light of other wavelengths and the light to be edited after the change of the polarization direction from the frequency domain to the time domain; wherein the light of other wavelengths is the light in the same light beam except the light to be edited;

[0041] The spatial editor 3 is used to receive the light of other wavelengths and the light to be edited after the change of the polarization direction, and edit the light to be edited after the change of the polarization direction.

[0042] The controller controls the light source to emit a light beam, and the light is transmitted to the first grating. The light source used in the embodiment of the application is a supercontinuum light source. The first grating is used to convert the same light beam emitted by the light source from the time domain to the frequency domain to realize the spatial separation of different wavelengths of light in the same light beam, so the first grating here cannot be replaced by a mirror. The diffraction angles of different colors of light are different, so the light of different wavelengths in the light source can be distinguished in space by the first grating, for example, after passing through the first grating, the light emitted by the light source is separated in the order of red light, orange light, yellow light, green light, blue light, indigo light, and purple light from bottom to top.

[0043] The polarizer is added after the first lens of the 4f optical system to change the polarization direction of the light to be edited, and the second grating in the 4f optical system combines the light of other wavelengths and the light to be edited after the change of the polarization direction from the frequency domain to the time domain, so that the light beam finally emitted from the 4f optical system contains the components to be edited with different polarization directions and other components without polarization conversion. The single light beam containing the light with the polarization direction converted and the light without the polarization conversion is incident into the spatial editor. The spatial editor edits the polarization light to be edited, so that the editing of the light to be edited can be realized. Assuming that the light source contains light with a wavelength of λ1, light with a wavelength of λ2, and light with a wavelength of λ3, for example, Figure 1In the embodiment, assuming that the polarizer changes the polarization direction of light with wavelength λ1, the polarization direction of light with wavelength λ1 is changed after the 4f optical system, while the polarization direction of light with wavelength λ2 and light with wavelength λ3 is not changed; then the light with wavelength λ1 whose polarization direction is changed, the light with wavelength λ2 and the light with wavelength λ3 whose polarization direction is not changed are incident into the spatial editor together; the spatial editor only edits the light with wavelength λ1 whose polarization direction is changed, and obtains edited light with wavelength λ1.

[0044] The number and position of the polarizer are not limited, and are determined according to actual conditions. For example, if the light with wavelength to be edited is only red light, one polarizer can be used, and the polarizer is placed in the transmission direction of the separated red light, so that the polarization direction of the red light is changed only by the polarizer; if the light with wavelength to be edited is red light and green light, two polarizers can be selected, and are placed in the transmission direction of the separated red light and the transmission direction of the separated green light respectively. In order to realize the same spatial domain editing of the red light and the green light, it is necessary to ensure that the polarization direction of the red light after passing through the polarizer is the same as the polarization direction of the green light after passing through the polarizer, then the single light beam containing the light without polarization conversion, the red light and the green light with the same polarization direction is incident into the second grating, the merging from the frequency domain to the time domain is realized, and finally the spatial editor is incident. The spatial editor edits the red light and the green light which need to be edited, and the edited red light and the edited green light are obtained.

[0045] The light beam spatial domain editing device provided by the embodiment comprises a spatial editor, a 4f optical system comprising a polarizer, and the 4f optical system and the spatial editor are sequentially arranged in the transmission direction of the light beam emitted by the light source. The first grating in the 4f optical system is used to convert the same light beam emitted by the light source from the time domain to the frequency domain to realize the separation of different wavelengths of light in space. The polarizer is arranged at the Fourier plane between the first lens and the second lens of the 4f optical system and is arranged in the transmission direction of the light to be edited in the same light beam, and is used to change the polarization direction of the light to be edited. The second grating in the 4f optical system is used to combine the light of other wavelengths and the light to be edited with the changed polarization direction from the frequency domain to the time domain. The other wavelengths of light are the light in the same light beam except the light to be edited. The spatial editor is used to receive the light of other wavelengths and the light to be edited with the changed polarization direction, and edit the light to be edited with the changed polarization direction. In the device, the reflection or refraction of the light beam is not required, the requirement for the device is low, and the energy loss is small. The editing process is carried out and completed in the same light beam (i.e. single light beam), without the need for beam splitting and beam combining, and is not easily affected by the environment, so that the accuracy of the light beam spatial domain editing is improved. In addition, the first grating separates the multi-wavelength light beam emitted by the light source in space, so that the light of the wavelength to be edited can be accurately edited after passing through the polarizer and the spatial editor, and the accuracy of the light beam spatial domain editing is further improved.

[0046] On the basis of the above embodiment, if the edited light beam obtained after one editing of the light beam to be edited is not the required light beam, or if the light of another wavelength needs to be edited after one editing, the preferred embodiment is that the light beam spatial domain editing device further comprises a mirror.

[0047] The mirror is used to receive the edited light beam after the spatial editor and reflect the edited light beam to the first grating.

[0048] Figure 2 A schematic diagram of a light beam spatial domain multi-component editing device provided by the embodiment of the application is shown in FIG. 2. Figure 2 As shown in FIG. 2, the light beam spatial domain multi-component editing device comprises a 4f optical system 2, a spatial editor 3 and a mirror M. Figure 2 In the 4f optical system 2, the light emitted by the light source 1 is incident to the first lens L1 of the 4f optical system 2 after the first grating G1 in the 4f optical system 2 to perform Fourier transform, and then the polarization conversion is performed by the movable polarizer P arranged at the Fourier plane to make the polarization direction different from the rest of the light.

[0049] The single light beam comprising different polarization directions is incident to the spatial editor 3 after the second lens L2 and the second grating G2 to edit the light converted by the polarizer P in the previous step.

[0050] The edited light beam is reflected by the mirror M and then enters the 4f optical system 2 again, and the polarizer P is adjusted to the position of the component to be edited for polarization conversion; the light after polarization conversion is subjected to spatial editing again by the foregoing steps, and this process can be edited multiple times until the edited light beam meeting the requirements is emitted through the spatial editor 3.

[0051] The light beam spatial domain editing device provided in the embodiment is used for editing the light beam, and the edited light beam is transmitted to the mirror, and then enters the 4f optical system including the polarizer, and then enters the spatial editor again for editing, so that the edited light beam meeting the requirements can be obtained.

[0052] The light beam spatial domain editing device is described above, and the embodiment further provides a light beam spatial domain editing system including the light beam spatial domain editing device.

[0053] The light beam spatial domain editing system provided in the embodiment has the same technical features as the light beam spatial domain editing device described above, and the embodiment of the light beam spatial domain editing device has been described in detail above, and the embodiment of the light beam spatial domain editing system will not be described here again, and has the same beneficial effects as the light beam spatial domain editing device mentioned above.

[0054] In the above-described embodiment, the edited light beam is reflected by the mirror, and then enters the 4f optical system again, and then enters the spatial editor for re-editing, so that the light beam after multiple editing is obtained. In the embodiment, another system capable of achieving multiple editing is further provided. The light beam spatial domain editing device in the light beam spatial domain editing system is multiple.

[0055] The edited light beam obtained by the spatial editor in the current light beam spatial domain editing device is transmitted to the first grating in the next light beam spatial domain editing device of the current light beam spatial domain editing device.

[0056] It should be noted that, for convenience of description, it is considered that the two gratings included in each light beam spatial domain editing device are respectively a first grating and a second grating. In each light beam spatial domain editing device, there is included a 4f optical system including a polarizer and a spatial editor. However, in practice, in order to distinguish the gratings in different light beam spatial domain editing devices, the gratings in the first light beam spatial domain editing device can be respectively described as a first grating and a second grating, the gratings in the second light beam spatial domain editing device can be respectively described as a third grating and a fourth grating, and the gratings in the Nth light beam spatial domain editing device can be described in order according to the transmission order of the light beam.

[0057] Here, taking two light beam spatial domain editing devices as an example, the process of achieving multiple editing by the light beam spatial domain editing system is described.Figure 3 The schematic diagram of the light beam spatial domain multi-component editing device provided for another embodiment of the present application is shown. As shown, the device comprises a first light beam spatial domain editing device and a second light beam spatial domain editing device. The first light beam spatial domain editing device comprises a first 4f optical system 210 comprising a first polarizer P1, and a first spatial editor 31. The second light beam spatial domain editing device comprises a second 4f optical system 211 comprising a second polarizer P2, and a second spatial editor 32. Figure 3 In the device, the light emitted by the light source 1 is reflected by the first grating G1 of the first 4f optical system 210, and then is incident to the first lens L1 to perform Fourier transform. The light after the Fourier transform is polarized by the first polarizer P1 placed at the Fourier plane, and then is incident to the second lens L2 and the second grating G2, and then is incident to the first spatial editor 31 to perform spatial domain editing. The edited light beam is incident to the third lens L3 of the second 4f optical system 211, and then is incident to the fourth lens L4 and the fourth grating G4, and then is incident to the second spatial editor 32 to perform spatial domain editing. Figure 3 In the device, the light emitted by the light source 1 is reflected by the first grating G1 of the first 4f optical system 210, and then is incident to the first lens L1 to perform Fourier transform. The light after the Fourier transform is polarized by the first polarizer P1 placed at the Fourier plane, and then is incident to the second lens L2 and the second grating G2, and then is incident to the first spatial editor 31 to perform spatial domain editing. The edited light beam is incident to the third lens L3 of the second 4f optical system 211, and then is incident to the fourth lens L4 and the fourth grating G4, and then is incident to the second spatial editor 32 to perform spatial domain editing.

[0058] In the device, the polarization direction of the red light is changed by the first polarizer P1 in the first light beam spatial domain editing device, the red light is edited by the first spatial editor 31, and the edited red light is obtained. The polarization direction of the green light is changed by the second polarizer P2 in the second light beam spatial domain editing device, the green light is edited by the second spatial editor 32, and the edited green light is obtained. Figure 3 It should be noted that,

[0059] In the device, only two light beam spatial domain devices are included in the light beam spatial domain editing system, and in practice, multiple 4f optical systems can be cascaded according to actual requirements. Figure 3 In the device, the first light beam spatial domain editing device is used to polarize and edit the light with a wavelength of λ1, and the second light beam spatial domain editing device is used to polarize and edit the light with a wavelength of λ2. In practice, the second light beam spatial domain editing device can further edit the light with a wavelength of λ1 again until the light meets the requirements. The above is only a preferred embodiment of the present application, and any equivalent changes and modifications within the scope of the present application should be included in the scope of the present application. For example, Figure 3 The device provided in the present application combines Figure 3 The device provided in the present application also falls within the protection scope of the present application. Figure 2

[0060] ​The light beam spatial domain editing system provided in the embodiment comprises a plurality of light beam spatial domain editing devices, so that the same wavelength or different wavelength light can be edited, and further, the required edited light beam can be obtained; in addition, the simultaneous editing of different wavelength light can be realized.

[0061] On the basis of the above embodiment, the number of polarizers is not limited, and the number of polarizers in each light beam spatial domain editing device is multiple.

[0062] The number of polarizers in each light beam spatial domain editing device is multiple, and each polarizer is placed in the transmission direction of the light to be edited. For example, if the red light and the green light are edited simultaneously, two polarizers can be added after the first lens. The first polarizer is placed in the transmission direction of the red light to change the polarization direction of the red light; the second polarizer is placed in the transmission direction of the green light to change the polarization direction of the green light. The red light and the green light after changing the polarization direction are edited by the spatial editor to obtain the edited red light and the edited green light. It can be seen that the editing of the red light and the green light is realized simultaneously.

[0063] The number of polarizers in each light beam spatial domain editing device is multiple, so that the editing of multiple wavelength light can be realized after each light beam spatial domain editing device. Compared with the mode in which only one polarizer is included in each light beam spatial domain editing device, the editing efficiency of different wavelength light can be improved.

[0064] In the above embodiment, there are multiple polarizers in each light beam spatial domain editing device. In practice, the number of polarizers in each light beam spatial domain editing device is one, and the corresponding polarizer in each light beam spatial domain editing device is used to change the polarization direction of the light to be edited.

[0065] As shown in the above Figure 3 The first polarizer in the first light beam spatial domain editing device changes the polarization direction of the light with wavelength λ1, and the second polarizer in the second light beam spatial domain editing device changes the polarization direction of the light with wavelength λ2.

[0066] In the embodiment, there is only one polarizer in each light beam spatial domain editing device, and only the polarization direction of light with one wavelength is changed in each light beam spatial domain editing device. Compared with the mode in which the polarization direction of light with different wavelengths is changed by multiple polarizers in one light beam spatial domain editing device, the polarization component of light with one wavelength may coincide with the polarization component of light with another wavelength, so that the editing of light with one wavelength also edits light with another wavelength. However, the mode of the embodiment can realize the polarization of light with a specific wavelength and the editing of the light with the wavelength.

[0067] The above describes an embodiment of a beam spatial domain editing device and a beam spatial domain editing system. This embodiment also provides a beam spatial domain editing method, applied to a beam spatial domain editing device including: a spatial editor and a 4f optical system containing a polarizer, wherein the 4f optical system and the spatial editor are located sequentially in the transmission direction of the beam emitted by the light source; the polarizer is located at the Fourier surface between the first lens and the second lens of the 4f optical system, and is located in the transmission direction of the light to be edited in the same beam; Figure 4 A flowchart of a beam spatial domain editing method provided in this application embodiment is shown below. Figure 4 As shown, the method includes:

[0068] S10: The first grating in the 4f optical system converts the same light beam emitted by the light source from the time domain to the frequency domain to achieve spatial separation of light of different wavelengths of the same light beam;

[0069] S11: Change the polarization direction of the light to be edited using a polarizer;

[0070] S12: The light of other wavelengths and the light to be edited after the polarization direction has been changed are merged from the frequency domain to the time domain through the second grating in the 4f optical system; wherein, the light of other wavelengths refers to the light in the same beam other than the light to be edited;

[0071] S13: Receive light of other wavelengths and light to be edited after its polarization direction has been changed through the spatial editor, and edit the light to be edited after its polarization direction has been changed.
