BEAM PROFILERS - Fiber lasers pose special challenges for beam profiling

摘要

Fiber lasers are increasingly used to mark, machine, melt, or other-wise modify materials with progressively more intricate patterns and shapes. Such applications use lasers ranging from a few watts to a few kilowatts of power, and a key advantage of fiber lasers in such applications is a more Gaussian beam profile than other lasers of comparable power. Thus, effective beam profiling will play an ever more important role in evaluating fiber lasers, predicting their effects on associated optics, and helping fiber-laser technology reach its full potential.
