Femtosecond laser cutting is a processing method that uses femtosecond laser technology to cut materials. A femtosecond laser is a laser with an ultra-short pulse width (in the picosecond (one trillionth of a second) to femtosecond (one quadrillion second) range) that is capable of emitting high energy in a very short time.
In the process of femtosecond laser cutting, femtosecond laser pulses are instantaneously irradiated to the surface of the material, forming a spot of light with high energy density. Under the action of light spots, the atoms and molecules on the surface of the material are rapidly ionized and excited to form a high-density electron plasma, resulting in a rapid cooling process. Femtosecond lasers differ from conventional lasers in that they do not generate much heat during processing, and this non-thermal cutting method is known as "cold cutting" or "photomechanical cutting".
At present, the mainstream laser control system solution in the industry is motion control card, so the femtosecond laser control system is also called femtosecond laser control card.
Femtosecond lasers use motion control cards as a solution, which has the following advantages:
1.High-precision control: The motion control card has high-precision position and speed control capabilities, and can monitor and adjust the operating status of motion equipment in real time.
2.Fast real-time response: The motion control card adopts high-speed data transmission and processing technology, which can respond to control instructions in real time to ensure the stability and accuracy of the motion system.
3.Multi-axis control: Motion control** often supports multi-axis control, which can control multiple motion devices at the same time to achieve complex coordinated movements.
4.Powerful scalability: Motion control** often supports a variety of interfaces and communication protocols, and can be flexibly connected and exchanged with other devices, with strong scalability.
5.Programmability and flexibility: Motion control** often has programming interfaces and development tools, allowing users to write control programs as needed to achieve personalized control strategies.
Some people in the industry may not be able to correctly distinguish femtosecond, picosecond and other different laser types, so they are collectively referred to as ultrafast laser, this statement can not be considered wrong, can only be said to be not rigorous, in fact, femtosecond and picosecond although the same ultrafast laser, but the two are quite different, the required control system is also different, in the actual choice, we still have to carefully discern and choose the solution they really need.
