1. Laser output good beam quality, including mode and mode stability;
2. Whether the output power of the laser is large enough (this is the key to the speed and effect) and the energy is stable (usually requiring a stability of 2%, and in some cases 1%, in order to process the desired effect);
3, The laser should have high reliability, should be able to work continuously in harsh industrial processing environment;
4, the laser itself should have good maintenance, fault diagnosis, and chaining function, downtime should be short;
5, the operation is simple and convenient, the control key function is clear, can reject the illegal operation, protect the laser from damage. In addition, laser marking machine prices are also important factors to consider.
