UV laser is a kind of laser that produces ultraviolet beam. At present, excimer lasers and all solid state lasers are mainly used in laser micromachining. Because of its short wavelength, UV laser can be absorbed by most materials and has advantages in laser material processing. With the deepening of the research on UV laser, the application field of UV laser continues to expand. At present, it has been applied in many fields, such as food, pharmaceutical packaging, electronics, semiconductors and so on.
Solid state UV lasers are divided into xenon lamp pumped UV lasers, krypton lamp pumped UV lasers and new laser diode pumped all solid state lasers. Generally, the integrated design is adopted, which has the characteristics of small light spot, high repetition frequency, reliable performance, strong heat dissipation capacity, good beam quality and stable power.
UV laser has unique properties. It is called "cold" processing. The laser with shorter wavelength and pulse width and low M2 (beam quality) can create a more focused spot and maintain the minimum heat affected zone (HAZ). In the marking application, it can maintain the original object to the greatest extent and reduce the damage during processing. Such as glass marking, ceramic carving, glass punching, soft circuit board cutting and other applications, which are loved by processing enterprises.
UV laser is a kind of light invisible to the naked eye, with small spot (0.07mm), narrow pulse width, fast speed and high peak output. Local irradiation of the workpiece with laser high-energy laser can gasify the surface material or produce photochemical reaction of color change, leaving a permanent mark. High power, high pulse repetition rate (PRF), pulse shaping and pulse splitting can all contribute to improving the productivity of micromachining.
Industry analysts said that UV lasers are widely used. With the development of downstream 3C industry, the market demand for UV lasers shows a fluctuating growth trend. In terms of products, UV laser products above 10W are favored, while 30W UV laser products have a better development prospect. In terms of market competition, the UV laser market is relatively concentrated, and due to the high entry threshold and downstream replacement cost of the industry, the competition pattern of the UV laser market is relatively stable, and it is difficult for new entrants to expand the market.
