Picosecond and femtosecond laser cutting equipment refer to the laser cutting equipment with the pulse width as picosecond. It has the characteristics of picosecond ultra short pulse width, adjustable repetition rate, high pulse energy, and has more and more extensive applications in biomedicine, optical parametric oscillation, biological microscopic imaging, and has gradually become an increasingly important tool in modern biological imaging and analysis systems.
The remarkable progress of picosecond and femtosecond laser technology has made it a reliable tool for industrial micro machining, which could not be completed by other methods before. The picosecond pulse width can be compared with the electro optical relaxation time, which is short enough to "cold" ablate the material
Specific advantages of picosecond and femtosecond laser cutters:
1、 Mild carbonization
The laser pulse width is less than 10 picoseconds, the carbonization range is very small, and the carbonization phenomenon can hardly be seen.
2、 Faster
The picosecond repetition rate is very high, reaching megahertz. At the same time, the galvanometer speed can reach 3000 mm/s, and the comprehensive speed of Kobe nanosecond light is increased by 1.5~2 times.
3、 More refined cutting effect
Picosecond processing uses small single pulse energy, high-frequency processing, fine carving, and the processing surface is more refined and smooth.
4、 More processing materials
In addition to traditional processing of polymer materials and copper foils for circuit boards, picosecond and femtosecond laser equipment can also process ceramics, silicon chips, Teflon, etc.
