A good engraving and cutting laser must have special optical capabilities to remove the pleat behind the material, not deform the material due to heating and greatly reduce the work deficit. These capabilities will be mentioned in this article.
1) Do not make grooves
2) Do not fold and do not deficit
3) The metal does not deform due to heat
4) Being able to cut in different depths at different positions, to create different colors on the work
Vanadite solid state lasers, which are the latest technology in the United States, have four advantages over Yag lasers:
1. Their pulse duration is more than 10 times shorter than Yag lasers. This causes the material to be cut before heating, deforming and pleating. In addition, the impulse of the light pulse is 10 times stronger.
2. The diameter of their spot is about 10 times smaller than Yag lasers. This makes them to cut much sharper and more accurate than yag lasers.
3. The output beam quality of these lasers is many times better than Yag lasers, which makes the cut to be sharper and greatly reduces the pleat and work deficient.
4. These types of lasers can also be cooled by air without the need for chillers and cooling liquids.
