Abstract

As solid-state lasers, fiber lasers demonstrate the same types of operating regimes. However, the physical processes that take place in gain media (the fiber core) create challenges that are unique to fiber lasers, mainly because of their small cross-section dimensions compared with other active media (typical core diameter of diffraction-limited fiber lasers: 6–30 μm) and the very long length of gain material (typically in the multimeter scale). In comparison, semiconductor lasers also have gain material with very small cross-sectional dimensions, but the gain material length is on the submillimeter scale. In addition, because of the rare-earth nature of fiber lasers’ active ions, energy storage in fiber laser systems is high. In addition to possibility of high energy/peak power pulse production by fiber lasers, these characteristics create challenges in nonlinear processes and damage processes, which have to be addressed during fiber laser design and development.
