To understand the advantages of pulse width adjustable fiber laser marking machines, let's start with the basic concepts.
Laser marking machineA laser marking machine is a device that uses a laser beam to permanently mark surfaces of various materials. The effect of marking is to expose deep substances through the evaporation of surface materials, thereby engraving exquisite patterns, trademarks, and text. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines, and YAG laser marking machines. Currently, laser marking machines are mainly used in situations that require more precision and accuracy. Applied to electronic components, integrated circuits (ICs), electrical appliances, mobile communication, hardware products, tool accessories, precision instruments, glasses and clocks, jewelry and accessories, automotive parts, plastic buttons, building materials, PVC pipes.
Fiber laser marking machineIt is a laser marking machine using fiber lasers. Fiber laser has become a hot topic in laser physics research in recent years, and it is unanimously considered as a new generation product that has the potential to completely replace solid-state lasers. Fiber laser refers to a laser that uses rare earth element doped glass fiber as a gain medium. Fiber laser can be developed based on fiber amplifier: under the action of pump light, high power density is easily formed inside the fiber, causing the laser energy level of the laser working substance to "reverse the number of particles". When a positive feedback loop (forming a resonant cavity) is appropriately added, laser oscillation output can be formed.
What does it meanAdjustable pulse widthWhat about it? Firstly, we need to know what pulse width is.
Pulse width refers to the duration of a pulse, not the size of the light spot. Don't make a mistake. What is pulse width adjustable. That is to say, how long can the duration of a pulse be adjusted. Pulse width, also known as pulse width, refers to the duration of a single pulse. Therefore, it is a unit of time measurement, with various magnitudes such as milliseconds (ms), microseconds (us), nanoseconds (ns), picoseconds (ps), femtoseconds (fs), etc. The smaller the magnitude, the shorter the duration of laser action. So some people may ask, what are the benefits of adjustable pulse width? Of course there are benefits. By the way, the difference between pulsed laser and continuous laser can be mentioned here. Interested friends can find articles before urination to read. The fiber laser marking machine uses pulsed laser. The general pulse width is fixed. However, fixed pulse width fiber laser marking machines cannot produce black alumina, while adjustable pulse width fiber laser marking machines can easily achieve this. This is an example in terms of application. Due to the addition of adjustable pulse width, fiber laser marking machines have become more widely used in terms of application scope.
Nowadays, the application of fiber laser marking machines with adjustable pulse width is mostly inBlack is printed on the anodized aluminumThe marking is not possible with regular fiber laser marking machines.
In short, the pulse width adjustable fiber laser marking machine has a wider range of applications and is more practical than ordinary fiber laser marking machines. Of course, the price is also slightly higher, and everyone can choose according to their own product and processing requirements.
