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.
