What are the powers of high power ultraviolet laser and what is the difference?

The most used ones on the market are 3W and 5W, and the marking effect is different depending on the power, but it does not mean that the high power is good, and the low power is not good. Material properties, only 3W UV laser marking machine cannot be adjusted to 5W marking, but 5W UV laser marking machine can be adjusted to 3W power usage. In terms of cost performance, it is generally recommended to buy 5W ones to avoid insufficient power for subsequent use.
