How efficient is laser deep engraving?
Date:2021-05-26Source:Original article

The MOPA Fiber Laser is used to mark text, vector diagrams, two-dimensional codes, pictures, etc. on different materials, which are generous and beautiful, durable and wear-resistant. Deep carving is a typical application of MOPA technology.

According to the different requirements of various industries for deep engraving technology, MOPA fiber lasers of different powers are used. Raycus launched a new 200W MOPA fiber laser: RFL-P200MX. In metal materials, especially carbon steel, copper and other dense materials, it has obvious advantages in deep carving efficiency.



● Pulse mode and continuous mode are optional;

● Single pulse energy is as high as 1.5mJ;

● Wide adjustable frequency range;

● Multiple pulse widths are optional;

● A wider range of process applications



We tested the efficiency of deep engraving on the RFL-P200MX on three different materials. The test pattern area is 48mm², and the test efficiency and shading roughness are as follows:



Compare the efficiency of deep carving on pure aluminum with MOPA lasers of different powers. The test pattern area is 48mm², and the test efficiency is shown in the table below:



Its deep engraving efficiency ratio is 20W:50W:100W:200W=1:3:9.5:25.5, and the RFL-P200MX deep engraving efficiency is much higher than 20-100W lasers.




RFL-P200MX deep carving 12s, depth 1.2mm




Case number one

20 characters, character height 8mm, depth 0.2mm, efficiency 18s




Case three

Metal nameplate information marking

Several characters, broken paint, depth <0.1mm, efficiency 16s




Case four

Carbon steel tubing marking

Marking depth> 0.2mm, marking area> 600mm²

The efficiency comparison is as follows:
