Abstract

Fiber laser is a kind of solid state lasers using optical fiber which enables light amplification by doped rare earth elements in a core of the optical fiber. Yb-doped silica glass fiber is used in a kW-class high power fiber laser system. Yb-doped fiber laser is often used in laser processing, such as printing, marking and metal processing, and therefore, it has become the mainstream in the industrial field. Yb-doped silica fiber laser, however, has a problem of reducing the fiber laser performance due to the photo-darkening (PD) effect. In recent years, many researchers have been researching PD effect. For example, Chavez et al. checked absorption spectra of an Al co-doped Yb fiber in the visible region after high power laser irradiation [1]. They concluded that PD is generated by valence state changes in Yb from Yb3+ to Yb2+.
