It is necessary to consider the mechanism of material and laser action. The lasers with different indexes are mainly divided into the following aspects:
1. Looking at the wavelength, different materials absorb different wavelengths, such as processing plastics. For wood, please choose CO2 (10.6um) laser; for metal processing, please choose fiber or YAG laser (1um); for processing certain medical materials, you may choose erbium-doped laser (2um); ultraviolet or green light, processed in hard and brittle materials. Use more (this is not a problem of material absorption)
2. Look at the power, which is said to be continuous, the pulse can not only look at the average power, the use of high power is usually based on the thermal effect of the laser to melt the material, which is Cutting (metal sheet metal cutting, not hard and brittle materials), welding, cladding and other applications are usually the same;
3. Look at the beam quality, with fiber laser, multimode (relatively low difficulty, relatively poor beam quality) and single Models (difficult, good beam quality, small focus can be focused), they have their own advantages in industrial processing, generally in pursuit of cutting speed Or the menu mode with a long distance; the general selection of multi-mode for processing thickness (the beam is better, but with the continuous improvement of the single-mode level, the supporting process is mature, and the single-die thick-plate cutting is gradually applied);
4. Talk about pulsed lasers. Pulsed lasers involve many indicators, pulse energy, average power, pulse width, and repetition frequency. These indicators are mutually constrained. Pulse energy and pulse width together determine the peak power. The laser of the home can adjust the above indicators at will, and the marking is not to be carved. Let's talk about the laser cleaning which is relatively hot now. The mechanism of laser cleaning is very complicated, there are thermal effects, field effects, plasma, etc., theoretically, it is not damaged. In the case of a substrate, the higher the single pulse energy, the better the cleaning effect, the higher the repetition frequency, and the higher the cleaning efficiency; the other one is very fast, the ultra-fast laser has a very narrow pulse width, which is very high. The peak power can be processed before the thermal effect occurs, so it is called cold working, so it is especially suitable for hard and brittle materials such as glass and ceramics.
5. Finally, the laser is one of the cores of laser processing. The latter optical system such as focusing, collimation, and spot shaping is also crucial. Together with the laser, it determines the power density and energy distribution. The laser can only achieve good processing results with the back-end process.
