As a cutting-edge technology, ultraviolet laser has attracted extensive attention and research in recent years. Among them, 266nm ultraviolet laser, as one of the ultraviolet lasers, has unique advantages and application fields. In this paper, the principle, application and future development prospect of 266nm ultraviolet laser will be deeply discussed through the creation method of popular science.
What is a 266nm UV laser?
The 266nm ultraviolet laser is a device capable of emitting laser light in the wavelength range of 266 nanometers. It uses advanced laser technology to convert electrical energy into high-energy photons through a specific energy level transition process. Because its operating wavelength is in the ultraviolet spectrum, it has many characteristics that other wavelength lasers cannot match.
Principle and composition
The core component of the 266nm UV laser is a diode-pumped solid-state laser. It consists of a laser medium, a pump source and an optical cavity. The laser medium usually uses Nd:YAG (neodymium-doped alumina yttrium) crystals, while the pump source uses a high-power diode laser.
In the working process, the laser generated by the pump source is focused by the optical system and input into the laser medium. The laser medium converts the pumped laser into a higher energy laser through the process of stimulated radiation. After many reflections and amplification, the final ultraviolet laser output of 266nm wavelength is formed.
Application field
Biomedical science
266nm UV laser has a wide range of applications in the biomedical field. Its wavelength is in the peak position of DNA and protein absorption, and can be used for DNA sequencing, protein analysis and other studies. In addition, it can also be used in biological microscopy, laser surgery and other fields, providing an important tool for medical research and clinical diagnosis.
lithography
Lithography technology is an indispensable key link in the manufacture of integrated circuits. The short wavelength and high energy of the 266nm UV laser make it ideal for lithography. It enables micro-machining with smaller sizes and higher precision, helping to improve the performance and reliability of integrated circuits.
Laser display
With the development of display technology, there is an increasing demand for higher resolution and more realistic colors. 266nm UV laser can be used for laser projection display, by controlling the scanning and modulation of the laser beam, to achieve high resolution image display effect. This display technology has the characteristics of high color saturation and strong contrast, and is expected to be widely used in the future display equipment.
Development prospect
