Will UV Laser Applications Continue To Erupt In The 5G Ara?

Excellent UV laser performance, gradually becoming a new favorite in the market

The ultraviolet laser is a laser having a wavelength of 355 nm. Due to its short wavelength and narrow pulse characteristics, it can generate a very small focus spot and maintain a minimum heat affected zone, which is a kind of "cold processing", which allows it to process very accurately while minimizing mechanical deformation of the material. The advantage of UV lasers is that they can provide extremely fine machining results while maintaining good positioning accuracy.

At present, in view of the continuous improvement of laser processing efficiency and requirements for industrial applications, nanosecond ultraviolet lasers of more than 10W have become the new darling of the market. Therefore, high-power, narrow pulse width, and high repetition frequency medium- and high-power nanosecond ultraviolet lasers have been developed by various companies. Mainstream direction.

Ultraviolet lasers directly break the chemical bonds that connect the atomic components of a substance. This process of separating substances into atoms is a "cold" process that does not generate heat to the periphery. On the other hand, most materials can effectively absorb ultraviolet light and can be used to process materials that cannot be processed by infrared and visible lasers. High-power UV lasers are mainly used in high-end markets for fine processing, including flexible circuit board (FPCB), printed circuit board (PCB) drilling / cutting, ceramic material drilling and dicing, glass / sapphire cutting, LED substrate Circular scribing, special glass cutting, laser precision marking and other fields.

5G communication brings opportunities for laser applications

All major countries in the world are seeking the most advanced technology as a new economic growth point. China has formed its own competitiveness in the independent development of science and technology and can compete with Europe, the United States and Japan on the same stage. 2019 is the first year of domestic 5G pre-commercialization, and it is clear that 5G has become a hot industry today. Folding screens launched by many manufacturers in February attracted wide attention, but they have not yet been widely used. Our country and various industries are also very much looking forward to 5G can bring a new generation of communication experience and bring a new vitality to the consumer electronics industry, especially the huge demand for product upgrades on the mobile phone side. Under its construction, the digital economy covering online and offline, consumption and production, platforms and ecology will gain greater driving force.

Currently, China has more than 1 billion mobile phone users, and it has already entered the era of smart phones. Recalling that the fastest development stage of smart phones in China was probably 2010-2015, and many people forgot why this period has developed rapidly. Among them, There is a rapid transition of communication signals from 2G to 3G, and the contribution of 4G. During this period, smart phones were represented, including PC tablets, mobile wear, and other products, which brought real demand for laser precision processing. A number of companies that have made precision laser equipment have received good orders for ultraviolet lasers and ultrafast lasers. Demand has risen accordingly.

Ultra-short pulsed UV laser will be the trend

Lasers can be divided into infrared light, green light, ultraviolet light, and blue light according to the spectrum. Pulse time can be divided into microseconds, nanoseconds, picoseconds and femtoseconds. Ultraviolet light is obtained by three times the frequency of infrared light, which is much more costly and difficult. At present, various domestic manufacturers are basically mature in nanosecond UV laser technology. They already have fully domestic products in the range of 2-20 watts, and many performances such as power stability control are also relatively reliable. In the past two years, due to the market competition of UV lasers, the price has declined, which makes more people realize the advantages of UV laser processing. Like infrared lasers, as the heat source for precision machining, there are two aspects of future development: one is higher power, and the other is the development of ultra-short pulses.

In order to meet the improvement of industrial processing precision requirements, our company independently developed a 355nm end-pumped Q-switched laser. This product is small in size, compact in structure, light in power and low in power consumption. It has a laser as the base mode, good beam quality and high peak power. According to the use environment, this series of products are water-cooled. The excellent resonant cavity design achieves high power stability and stable pulse sequence. It can completely and adjust the laser power and repetitive frequency output at any time, which fully meets the requirements of industrial precision processing.
