Cameras are being used by machinery manufacturers to inspect tubes. The quality check takes only about half an second, and the rotations required are reduced. This allows the machine's productivity to be maintained as well as its 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.
