What are the materials that UV laser can perform quality marking on?

UV laser features short wavelength, short pulse width, high speed and high peak value. It has become one of the most trending industrial lasers in the current laser market. As UV laser technology develops, its application becomes wider and wider. Nowadays, the commonly seen materials that UV laser can perform quality marking on include plastic, glass, ceramics and metals.

UV laser marking on 3C product plastic

The advent of 3C products is the result of fast development of the electronics industry. To leave a permanent marking on the plastic surface of the electronics, many enterprises introduced the UV laser marking machine. When the UV laser marking machine is working, the working temperature is pretty low with fast speed and enables remote control via the computer to achieve high precision marking. It won’t cause distortion on the plastic materials, for it is non-contact. 

UV laser marking on metal

Many of you may know that most of the parts of PCB consists of precious metals, including gold, silver and copper. For these tiny parts, manufacturers would add their unique marking on the them for better differentiation. Traditional printing technique is hard to achieve precision marking. But with UV laser whose pulse width is only 15nm@30KHz, precision marking can be easily achieved. 

UV laser marking on glass

Glass is a commonly seen in the our daily life. We can often see some beautiful patterns on the glass. They don’t have any color, but they are very beautiful. And those patterns are made by using UV laser marking machine. UV laser marking machine is much faster than manual marking and is more efficient with smoother marking surface. 

UV laser machine can also be applied to FPC/PCB cutting, profile cutting, drilling and mobile phone shell cutting and produce clear characters and patterns. 

Currently, the most mature Ultraviolet laser technology is around 3-10W and is commonly used in industrial level laser micromachining. It can be used to cut wafer, ceramics, thin film and so on. It is believed that UV laser technology will be heading towards higher efficiency, higher power and higher precision.

Industrial semiconductor laser and its potential

 Laser technology is gradually known by more and more people and has rapid development in the past few decades. Its major application include industrial manufacturing, communication, medical cosmetology, entertainment and so on. Different application requires different wavelength, power, light intensity and pulse width of the laser source. In real life, few people would like to know the detailed parameters of the laser source. Nowadays, laser source can be classified into solid-state laser, gas laser, fiber laser, semiconductor laser and chemical liquid laser.

Fiber laser is no doubt the “star” among the industrial lasers in the past 10 years with huge application and fast growing speed. In some point, the development of fiber laser is the result of the development of semiconductor laser, especially the domestication of semiconductor laser. As we know, laser chip, pumping source and some core components are actually semiconductor laser. But today, this article talks about the semiconductor laser used in industrial manufacturing instead of the one used as the component. 

Semiconductor laser - a promising technique

In terms of electro-optical conversion efficiency, solid-state YAG laser and CO2 laser can reach 15%. Fiber laser can reach 30% and industrial semiconductor laser can reach 45%. That suggests that with same power laser output, semiconductor is more energy efficient. Energy efficiency means saving money and a product that can save money for the users tend to become popular. Therefore, many experts think that semiconductor laser would have a promising future with great potential. 

Industrial semiconductor laser can be classified into direct output and optical fiber coupling output. Semiconductor laser with direct output produces rectangle light beam, but it is easy to be affected by back reflection and dust, so its price is relatively cheaper. For semiconductor laser with optical fiber coupling output, the light beam is round, making it hard to be affected by the back reflection and dust problem. What’s more, it can be integrated into robotic system to achieve flexible processing. Its price is more expensive. Currently, global industrial use high power semiconductor laser manufacturer includes DILAS, Laserline, Panasonic, Trumpf, Lasertel, nLight, Raycus, Max and so on. 


Semiconductor laser has wide applications

Semiconductor laser is less often used to perform cutting, for fiber laser is more capable. Semiconductor laser is widely used in marking, metal welding, cladding and plastic welding. 

In terms of laser marking, using semiconductor laser below 20W to perform laser marking has become pretty common. It can both work on metals and non-metals. 

As for laser welding and laser cladding, semiconductor laser is also playing an important role. You can often see semiconductor laser being used to perform welding on the white car body in Volkswagon and Audi. The common laser power of those semiconductor laser is 4KW and 6KW. General steel welding is also an important application of semiconductor laser. What’s more, semiconductor laser is doing a good job in hardware processing, shipbuilding and transportation. 

Laser cladding can be used as a repair and refurbishment of the core metal parts, so it is often used in heavy industry and engineering machinery. Components like bearing, motor rotor and hydraulic shaft will have certain degree of wearing. Replacement could be a solution, but it costs a lot of money. But using laser cladding technique to add the coating to restore its original appearance is the most economical way. And semiconductor laser is no doubt the most favorable laser source in laser cladding. 

Professional cooling device for semiconductor laser

Semiconductor laser has compact design and in high power range, it is quite demanding for the refrigeration performance of the equipped industrial water chiller system. S&A Teyu can offer high quality semiconductor laser air cooled water chiller. The CWFL-4000 and CWFL-6000 air cooled water chillers can suit the need of 4KW semiconductor laser and 6KW semiconductor laser respectively. These two chiller models are both designed with dual circuit configurations and can work under a long time.

Fiber laser cutting application in electrical appliance industry

In electrical appliance industry, fiber laser cutting machine is mainly used to process the external sheet metal and the thin steel plate component. After employing this new technology, many electrical appliance factories have improved the product quality, lowered the production cost, reduced manual labor and boosted the productivity.

Laser cutting machine, especially fiber laser cutting machine is a high-tech processing technique in the past few decades. It can focus the energy to very tiny space and use high density energy to perform cutting in a non-contact, highly efficient and highly precise way. Comparing with traditional cutting technique, fiber laser cutting machine has higher cutting precision, lower roughness, higher utilization and higher productivity. 

Fiber laser cutting machine is powered by a fiber laser source which tends to generate a vast amount of heat during operation. What’s more, as the power of the fiber laser increases, the amount of heat generated will also increase. To ensure the normal working of the fiber laser cutting machine, the fiber laser inside needs some “special treatment” which means keeping it at a stable temperature range. 

S&A Teyu CWFL series recirculating laser chillers are specifically designed for cooling fiber lasers from 500W to 20KW. This series of fiber laser water chiller is designed with dual temperature control circuit independently controlling the temperature for the fiber laser and the laser head, which is space efficient and cost efficient.

What is the application of the first domestic ultrafast laser chiller?

Last October, LFSZ was held in Shenzhen World Exhibition & Convention Center. In this exhibition, a dozen of new laser products and technology were showcased. One of them was the first domestic ultrafast laser chiller which comes from S&A Teyu Chiller.

Ultrafast laser micromachining is experiencing a rapid development

The further development of industrial and high-end manufacturing is having more requirements for the precision. As an important manufacturing technique, laser manufacturing technique is now changing from the original nanosecond level to femtosecond and picosecond level. 

Since 2017, domestic ultrafast picosecond laser and femtosecond laser have been developing so fast with better stability and high power. The domestication of ultrafast laser breaks the dominance of the foreign suppliers and more importantly, lowers the purchasing cost. In the past, a 20W picosecond laser cost more than 1.1 million RMB. Such a high cost was one of the reasons why laser micro-machining wasn’t fully promoted at that time. But now, ultrafast laser and its core components are having lower price, which is good news for the mass application of laser micro-machining. As for the equipped cooling device, the first domestic ultrafast laser chiller was also born last year. 

The domestic ultrafast laser chiller has a great significance

Nowadays, the power of ultrafast laser has greatly improved, from 5W to 20W to 30W and 50W. As we know, ultrafast laser features non-contact processing and extremely high precision, so it does a good job in consumer electronics components processing, thin film cutting, brittle material processing and chemical & medical sector. The high precision and stability of ultrafast laser needs to be supported by a precise temperature control system. But as the laser power increases, the temperature stability is harder to ensure, making the processing result is less satisfactory. 

The continuous breakthrough of ultrafast laser results in high standard for the cooling system. In the past, ultra-high precision water chiller could only be imported from the foreign countries. 

But now, the CWUP-20 ultrafast laser chiller produced by S&A Teyu offers domestic users another alternative. This compact recirculating water chiller features ±0.1℃ temperature stability, which reaches the level of the oversea suppliers. At the same time, this chiller also fill the gap of this segment industry. CWUP-20 is characterized by a compact design and suitable for many applications. 

Ultrafast laser for glass cutting

The application of ultrafast laser is getting wider and wider. From silicon wafer, PCB, FPCB, ceramics to OLED, solar battery and HDI processing, ultrafast laser can be a powerful tool and its mass application has just started.

According to the data, the domestic mobile phone production capacity accounts for more than 90% of the total capacity of the world. Many people may not know that, the early application of ultrafast laser was mainly around mobile phone parts - phone camera blind hole drilling, camera slide cutting and full screen cutting. All these share the same material - glass. Therefore, ultrafast laser for glass cutting has become quite mature nowadays. 

Comparing with traditional knives, ultrafast laser has higher efficiency and better cutting edge when it comes to cutting glass. Nowadays, the demand of laser glass cutting in consumer electronics continues to grow. In the past 2 years, the sales volume of smart watch has continued to grow, bringing more opportunities to laser micro-machining technique. 

In this positive circumstance, S&A Teyu will continue to making contribution to domestic development of high-end laser micromachining business.
