The main disadvantage of these processes is. Even if it belongs to the low-power series in this laser pointer category. Their investment and operating costs remain high. Because the processing speed usually depends on the average power of the laser, for most industrial laser users, the cost of laser processing under actual surface coverage conditions may be too high. Recently, the pulse width range of mature nanosecond pulsed fiber lasers has been extended to subnanoseconds. What follows is a peak power capability that increases by an order of magnitude. This made it possible to develop a new laser surface processing process using a cost-effective long picosecond laser source.
Although these techniques are often referred to as green laser pointer surface treatments. From a mechanical point of view, these processes are closely related to laser marking. Because they are limited to the surface treatment of components, a combination of laser ablation and melting processes is often required. Figure 1 attempts to classify this wide range of processes using industry-accepted terminology and the main physical mechanisms involved. Change the laser marking surface area in a certain way. Make it a visual contrast with the unmarked area. Laser marking has important applications.
