High output power: Fiber lasers can be active several kilometers away and therefore can provide very high optical performance. They can withstand Kw levels of continuous output power thanks to the high ratio between fiber surface and volume, which allows efficient cooling.
Light is coupled into a flexible fiber which allows it to be easily delivered to a movable focusing element. This is crucial for laser cutting, welding, and folding of metals and polymers
High optical quality: The fiber’s wave guiding properties reduce or eliminate thermal distortion of the optical path.
Extended lifetime, and maintenance-free turnkey operation in comparison to older solid-state laser technology.
