What can a 30w fiber laser do
Fiber laser machines are better at cutting thin metals than other types of cutting machines. A fiber laser machine is capable of cutting thin metals up to 25mm (or 1 inch). Fiber lasers then start to cut metal less efficiently. To cut ticker metals larger than 25mm or 1 in., you would require a high power laser, which will cost you a lot more.
The beam quality of the 20W and 30W lasers is less than 1.5M2, while that of the 50W laser is less than 1.8M2.
