Exploration of Technology for Precise Power Supply and High Voltage Power Supply Adaptation for Helium-Neon Laser

Helium-neon laser is a type of laser widely used in medical, scientific, industrial and other fields. However, for helium-neon lasers, high-voltage power supply is the key to stable operation. Traditional high-voltage power supply has defects such as large precision deviation and poor stability, which directly affect the accuracy and stability of helium-neon lasers. Therefore, the exploration of the technology of precise power supply for helium-neon lasers and high-voltage power supply adaptation has become a hot research topic.

I. Defects of traditional high-voltage power supply

The traditional high-voltage power supply for helium-neon lasers adopts a transformer-based power supply method. The transformer realizes high-voltage output through the voltage ratio, but it has defects such as large precision deviation and poor stability. The magnetic hysteresis and core saturation of the transformer itself cause voltage fluctuations in the output, which will affect the stability of the helium-neon laser. In addition, the circuit structure of traditional high-voltage power supply is complex and bulky, which is not convenient for carrying and use.

II. Technology of precise power supply for helium-neon lasers and high-voltage power supply adaptation

To solve the defects of traditional high-voltage power supply, researchers have begun to explore the technology of precise power supply for helium-neon lasers and high-voltage power supply adaptation. The core of this technology is to adopt a capacitor-based power supply method, which stores electrical energy in capacitors and then boosts the energy to the required high voltage through a boosting circuit. Compared with the traditional transformer-based power supply method, the capacitor-based power supply method has the following advantages:
High precision: the capacitance value of the capacitor can be guaranteed by precise manufacturing technology, thus achieving high-precision voltage output.

Good stability: the stability of the output voltage of the capacitor is much better than that of the transformer-based high-voltage power supply.

Small size: the capacitor is small in size, which can realize the miniaturization and portability of the high-voltage power supply.

High energy efficiency: the energy efficiency of the capacitor is higher than that of the transformer-based high-voltage power supply, which can improve the efficiency of the helium-neon laser.

III. Application of technology of precise power supply for helium-neon lasers and high-voltage power supply adaptation

The technology of precise power supply for helium-neon lasers and high-voltage power supply adaptation has been widely used. For example, in the medical field, the precise power supply technology for helium-neon lasers and high-voltage power supply adaptation can be used in macular surgery, cataract surgery and other surgeries. In the scientific research field, this technology can be used in laboratory laser interferometers, laser spectrometers and other equipment. In the industrial field, this technology can be used in laser cutting, laser marking and other fields.

IV. Conclusion

The emergence of the technology of precise power supply for helium-neon lasers and high-voltage power supply adaptation provides a more stable and precise power supply method for the application of helium-neon lasers. The application of this technology not only improves the stability and efficiency of helium-neon lasers, but also further promotes the development of application fields for helium-neon lasers. Although there are still some problems with this technology, such as high cost and complex manufacturing technology, it is believed that these problems will be gradually solved with the continuous development and improvement of technology.
