According to the absorption characteristic of material to laser, laser markers can be divided into two large series: 1. Solid-state laser; 2. CO2 laser. Customers can choose different series of laser markers based on the materials characteristics. The following table lists the classification of commonly used materials.
|
Solid-state laser series (YAG/YVO4)(The followings are some materials applicable for solid-state laser) |
CO2 series (the followings are some materials applicable for CO2 laser) |
