Final Accuracy
Another consideration is the fiber laser’s briefcase-sized modules—they allow for redundancy. If one module has a problem, the resonator doesn’t shut down completely. The fiber laser is redundant in a way that the other modules can produce more power temporarily to support the down module until repairs can be completed—which, by the way, can be done in the field. Other times the fiber resonator can continue producing reduced power until repairs can be made. Unfortunately, if a CO2 resonator has an issue, the entire resonator is down, not just in a reduced-power mode.
It's a third of a full 20-foot (240") tube, making it convenient to create three pieces of stock. This allows you to still purchase full tube lengths without wasting any material
