What are the advantages of ultrafast laser?

To understand ultrafast laser, one has to know what laser pulse is. Laser pulse refers to the fact that pulse laser emits an optical pulse. To put it simply, if we keep the torchlight on, that means the torchlight is working continuously. If we turn on the torchlight on and turn it off immediately, that means an optical pulse emits.

Laser pulse can be extremely short, reaching nanosecond, picosecond and femtosecond level. For example, for picosecond laser pulse, it can emit over 1mlliion billion ultrashort pulse and this is called ultrafast laser. 

What are the advantages of ultrafast laser? 

When laser energy focuses in such a short time, the single pulse energy and the peak power will be extremely high and big. Therefore, when processing on the materials, ultrafast laser won’t cause melting or continuous evaporating to the materials which is often the case if long pulse width and low intensity laser is used. That means ultrafast laser can greatly improve the processing quality. 

In industrial sector, we often categorize laser as continuous wave laser, quasi-continuous wave laser, short pulse laser and ultrashort pulse laser. Continuous wave laser is widely used in laser cutting, laser welding, laser cladding and laser engraving. Quasi-continuous wave laser is suitable for laser drilling and heat treatment. Short pulse laser is appropriate for laser marking, laser drilling, medical and medical field. Ultrashort pulse laser can be used to even high-end industries, such as precision processing, scientific research, medical, military areas. 

The time when ultrafast laser interacts with material is very short, so it won’t bring heat effect to the surrounding materials. Therefore, ultrafast laser is also known as “cold processing”. Ultrafast laser can also work on any kind of materials, including metal, semiconductor, diamond, sapphire, ceramics, polymer, resin, thin film, glass, solar power battery and so on.

With the demand of high-end manufacturing, intelligent manufacturing and high precision manufacturing increases, ultrafast laser technology will meet the new opportunity in the coming future.

As the representative of precision manufacturing tool, ultrafast laser needs to be cooled down properly in order to maintain the superior processing quality. S&A Teyu mini recirculating chiller CWUP-20, also known for its high precision, is the most selected by the ultrafast laser users. That is because this ultrafast laser small water chiller features +-0.1 degree C temperature stability and low maintenance and energy saving. Plus, ultrafast laser mini recirculating chiller CWUP-20 is also very user-friendly, for the instruction to use is easy to understand.

What is the role of ultrafast laser played in consumer electronics?

If we say laser is a sharp knife, then ultrafast laser is the sharpest one. So what is ultrafast laser? Well, ultrafast laser is a kind of laser whose pulse width reaches picosecond or femtosecond level. So what is special about the laser of this pulse width level?

Well, let’s explain the relationship between laser processing precision and pulse width. Generally speaking, the shorter the laser pulse width, the higher precision will be reached. Therefore, ultrafast laser which features shortest processing time, smallest acting surface and smallest heat affecting zone is so much more advantageous than other kinds of laser sources. 

So what are the common applications of ultrafast laser? 

1.OLED screen cutting for smart phones;
2.Cutting and drilling of smart phone sapphire crystal and toughened glass;
3.Sapphire crystal of smart watch;
4.Large-sized LCD screen cutting;
5.Repair of LCD and OLED screen
......

Toughened glass, sapphire crystal, OLED and other consumer electronics components are generally of high hardness and brittleness or with complicated and intricate structures. And they are mostly quite expensive. Therefore, the yield must be high. With ultrafast laser, efficiency and yield can be guaranteed. 

Although currently ultrafast laser only accounts for a small portion of the whole laser market, its growing speed is twice as much as the whole laser market. At the same time, as the demands of high-end manufacturing, smart manufacturing and high precision manufacturing increase, the future of ultrafast laser industry is worth expecting. 

The current ultrafast laser market is still dominated by foreign companies like Trumpf, Coherent, NKT, EKSPLA, etc. But domestic companies are now gradually catching up them. Quite a few of them have developed their own ultrafast laser technology and promote their own ultrafast laser products. 

Ultrafast laser has showed its value in many areas. Limited to its accessories, the processing ability of ultrafast laser is yet to be fully developed.

Ultrafast laser chiller is one of them. As we know, the performance of water chiller decides the running status of ultrafast laser. The more stable with higher temperature control for the chiller, the more processing power of the ultrafast laser will achieve. Keeping that in mind, S&A Teyu has been working so hard to develop small water chiller specifically designed for ultrafast laser - - the CWUP series compact recirculating water chillers. And we did it. 

S&A Teyu CWUP series ultrafast laser small water chillers features ±0.1℃ temperature stability and cooling technology with this precision is pretty rare in domestic markets. The successful invention of CWUP series ultrafast laser compact recirculating water chillers fills the vacancy of ultrafast laser chiller in the domestic market and provides a better solution to the domestic ultrfast laser users. Besides, this ultrafast laser compact recirculating water chiller is suitable for cooling femtosecond laser, picosecond laser and nanosecond laser and is characterized by small size, applicable in different applications.

The difference between ultrafast laser and traditional laser

Laser is known as one of the most important inventions in the 20th century and also called as “the fastest knife” , “the most correct ruler” and “the brightest light”. For the time being, laser has already become part of our life, including laser cutting, laser radar, laser cosmetic instrument and so on. In processing and manufacturing area in particular, laser cutting is more superior than traditional processing.

Traditional laser uses the thermal effect of the laser light to realize different kinds of processing. However, for ultrafast laser, it uses field effect to do the processing. This kind of processing can reach higher precision and won’t do any damage to the material surface. Therefore, it is often known as “cold processing”. 

The current market is mainly dominated by femtosecond level or picosecond level ultrafast laser. In fact, femtosecond and picosecond are time unit and they represent very short time. Therefore, the duration in which the ultrafast laser is working on the material is quite short. 

Another features of ultrafast laser is ultrahigh instant power. The instant power is so high that it can ionize the material and break the molecular bond of the material. With the above-mentioned features, ultrafast laser can not only reach ultrahigh precision, high quality and high durability. 

The current domestic trend is now heading from low end to high end. As the fantastic tool for high end micromachining, ultrafast laser is having faster development than traditional laser.

However, you may not know that ultrafast laser is quite sensitive to the temperature and its precision is affected by the temperature control. To maintain the precision of the ultrafast laser, it is suggested to equip the laser with ultrafast laser compact water chiller. S&A Teyu develops CWUP series ultrafast laser small water chillers which can provide ±0.1℃ temperature stability and continuous cooling for the ultrafast laser up to 30W. They support Modbus-485 communication protocol which can realize the communication between laser and the chiller.
