TECHNICAL FIELD
[0001] The application relates to a low-power specific parameter single-beam light source acquisition device and method and energy-saving application thereof in magneto-optical detection. BACKGROUND
[0002] In current MRAM (Magnetic Random Access Memory, a non-volatile magnetic random memory) process detection, magneto-optical detection technology has become an important means for detecting material properties or magnetic field distribution due to its unique advantages. Especially in the background of extremely high requirements for the interface flatness of the magnetic layer and the tunnel layer in MRAM, traditional mechanical detection methods are difficult to meet the high-precision requirements of super-large integrated circuits due to their limitations. Therefore, the magneto-optical detection technology can be applied to MRAM process detection, but special attention should be paid to the light splitting technology and a series of optical path designs to achieve the purpose of adjusting the detection effect. However, how to simply obtain a single-beam light source with specific parameters (such as wavelength, light intensity and spatial distribution, etc.) has become a major challenge for this technology.
[0003] Traditional light sources such as white light sources or monochromatic light sources have certain limitations in meeting specific parameters, such as limited wavelength range, unstable light intensity and difficult light beam adjustment, etc., which will affect the performance and reliability of the magneto-optical detection system. In view of this, it is urgent to propose a low-power specific parameter single-beam light source acquisition method and its energy-saving application in magneto-optical detection. SUMMARY
[0004] In order to solve the problems of the prior art, the application provides a low-power specific parameter single-beam light source acquisition device and its energy-saving application in magneto-optical detection, which not only focuses on obtaining a single-beam light source with specific parameters through specific light source acquisition technology and light beam adjustment technology, but also integrates the concepts of energy saving and low power consumption into each link of magneto-optical detection.
[0005] The application adopts the following technical solutions:

[0007] The laser emitter is connected with a current controller for generating a single beam laser source; an off-axis converter is used to parallelize its light and become a parallel beam; a wavelength selector is used to select the appropriate beam wavelength according to specific wavelength requirements; an attenuator is used to adjust the beam intensity; a light chopper is used for light intensity modulation; a collimator is used to adjust the direction and shape of the beam to make it a parallel beam; a polarizer system is used to select a specific polarization direction or change the polarization state of the beam; a filter system is used to adjust the wavelength range of the beam; and a stabilizer is used to adjust the output of the light source to maintain its stability and consistency.
[0008] The present application has the following characteristics:
[0009] Specific light source acquisition technology: By selecting appropriate light source devices such as lasers, LEDs, etc., and using optical elements such as filters, anisotropic materials, etc., a single beam light source with specific parameters is obtained. The effect of current is used to establish the connection of magneto-optical while obtaining stable parameters.
[0010] Wavelength range adjustability of the present application: Different combinations of light source devices and filters can achieve a wide range of wavelength selection to meet the specific wavelength requirements in magneto-optical detection.
[0011] Light intensity stability: The specific light source acquisition technology can provide stable light intensity output, reducing the influence of light intensity fluctuations on magneto-optical detection results.
[0012] Beam adjustment technology: By using optical elements such as lenses, prisms, polarizers, etc., the light beam of the light source is adjusted and optimized.
[0013] The advantages of this technical means include:
[0014] Spatial distribution control: The beam adjustment technology can achieve spatial distribution control of the light source beam, making it match the requirements of the magneto-optical detection system, improving the sensitivity and accuracy of detection.
[0015] Beam focusing and direction: By using optical elements such as lenses or prisms, the light beam of the light source can be focused and directed, making it more suitable for the needs of the magneto-optical detection system, improving the precision and stability of detection.
[0016] Through the above technical means, the present application solves the problems of obtaining a single beam light source with specific parameters and its application in magneto-optical detection in the prior art. The specific light source acquisition technology provides flexible wavelength range selection and stable light intensity output, meeting the requirements of magneto-optical detection for specific parameter light sources. The beam adjustment technology realizes precise control and optimization of the light source beam, improving the performance and reliability of the magneto-optical detection system.
[0017] The application discloses a low-power specific parameter single-beam light source acquisition device and an acquisition method thereof.
[0018] Preferably, the new light source technology is a specific wavelength light source based on LED or laser.
[0019] Preferably, the optical modulation technology includes precisely controlling the intensity, phase and polarization state of the light beam by using electro-optic modulators (EOM) and spatial light modulators (SLM).
[0020] Preferably, first, a laser emitter is used to generate a single-beam laser light source; the laser emitter can adjust the wavelength and power of the laser as needed.
[0021] The light beam output by the laser emitter is introduced into a wavelength selector, which selects an appropriate wavelength of the light beam according to specific wavelength requirements and filters out light of other wavelengths.
[0022] Through a collimator, the direction and shape of the light beam are adjusted to make it a parallel light beam, and the light beam is guided to the next optical component.
[0023] Before the light beam enters the next optical component, an attenuator is used to adjust the intensity of the light beam, which is to adapt to the requirements of magneto-optical detection on light intensity.
[0024] In order to maintain the stability of the light source, a stabilizer is used before the light beam enters the next optical component, which can adjust the output of the light source through feedback control and other methods to maintain its stability and consistency.
[0025] Next, the light beam passes through a polarizer system, which can select a specific polarization direction or change the polarization state of the light beam to adapt to the needs of magneto-optical detection.
[0026] The light beam passes through an off-axis converter to make its light rays parallel and become a parallel light beam, which helps the subsequent optical components to process.
[0027] Before the light beam enters the next stage, a light chopper can be used for light intensity modulation, which periodically blocks the light beam to produce light pulses, which is very important for subsequent signal processing and modulation.
[0028] The light beam enters a monochromator to select a light beam of a specific wavelength and filter out light of other wavelengths, which ensures that only the required wavelength participates in magneto-optical detection.
[0029] After the monochromator, the wavelength range of the light beam can be further adjusted using a filter system, which can select a specific wavelength range of the light beam by combining multiple filters;
[0030] Finally, the beam with specific parameters passes through the optical assembly and enters the magneto-optical detection device for detecting and analyzing the magneto-optical properties of the light beam passing through the MRAM sample. The magneto-optical detection device can measure parameters such as the polarization state or optical rotation of the light to obtain information about the MRAM process.
[0031] The present application can meet the requirements of specific wavelength range and light intensity in magneto-optical detection while achieving lower energy consumption, thereby improving the accuracy and energy efficiency of detection. Secondly, the spatial distribution of the light source can be optimized to better meet the requirements of the magneto-optical detection system, improving the sensitivity of detection. Finally, through the application of beam adjustment technology, precise control of the light source can be achieved, reducing errors and interference, thereby not only reducing energy consumption in the detection process, but also improving the stability and accuracy of magneto-optical detection.
[0032] An application of the above-mentioned low-power specific parameter single-beam light source acquisition device is applied to magneto-optical detection, improving the accuracy and sensitivity of magneto-optical detection, and reducing energy consumption while ensuring detection efficiency.
[0033] The core of the present application includes two aspects: one is to adopt new light source technology, such as specific wavelength light source based on LED or laser, to obtain stable and highly consistent single beam by precisely controlling the emission characteristics of the light source; the other is to combine advanced optical modulation technology, such as using electro-optic modulator (EOM) and spatial light modulator (SLM), to precisely control the intensity, phase and polarization state of the light beam, thereby realizing precise adjustment of the parameters of the detection light beam. In addition, an intelligent control system is used to dynamically manage the light source to adapt to different detection requirements, further reducing energy consumption.
[0034] The application of the present application can not only significantly improve the accuracy and sensitivity of magneto-optical detection, but also greatly reduce energy consumption while ensuring detection efficiency, meeting the requirements of green manufacturing and sustainable development. This innovative method not only has important significance for MRAM process detection, but also provides a new technical solution for other application fields that require high-precision magnetic detection.

[0040] 4. Increase the flexibility of the magneto-optical detection system: Specific light source acquisition technology provides wavelength range adjustability, allowing appropriate wavelength range to be selected according to specific requirements. This increases the flexibility of the magneto-optical detection system, allowing it to adapt to the needs of different materials and application scenarios.

[0070] Wavelength selection and adjustment:
[0071] One of the key points is to be able to select and adjust the wavelength of the light source, which can be achieved by using appropriate light sources or using wavelength selectors and optical components such as filters. By precisely controlling the wavelength of the light source, the requirements of specific wavelengths in magneto-optical detection can be met to measure and analyze the magneto-optical properties of the sample.

In magneto-optical detection, the stability and consistency of light intensity are very important for obtaining accurate measurement results. Therefore, ensuring stable output and appropriate light intensity adjustment of the light source is one of the key points.
[0074] Polarization control of light beam:
[0075] Magneto-optical detection usually involves measurement and analysis of the polarization state of the light beam. Therefore, one of the key points is to be able to control the polarization state of the light source, which can be achieved by using polarizer systems or other polarization control elements. By adjusting the polarization state of the light source, the requirements of specific polarization states in magneto-optical detection can be met, and accurate magneto-optical property measurement results can be obtained.
