1. Life: Because the laser tube is a consumable for the laser engraving machine, the life is the most important purchase index for users. The difference in life is mainly due to processing technology, and design technology is the main factor. Generally, the working life of domestic laser tube is about 1500 hours (60W as an example).

2. Laser energy: The maximum light intensity of laser tubes with different performances is different.

3. Spot quality: This performance is determined by the laser tube mode. The quality of the light spot is determined by many links in the production process. The quality of the light spot directly affects the performance when the user uses it.

4. Stability: Products with poor performance are prone to air leakage and explosion due to non-external factors.
