Abstract

An Fe²⁺-doped ZnSe saturable absorber mirror (SAM) were fabricated by electron beam evaporation technique. In the Fe²⁺-doped ZnSe SAM, Fe²⁺ was doped into the bragg stack, in which Fe²⁺:ZnSe served as both saturable absorber and high reflection layer. By using the Fe²⁺-doped ZnSe SAM in the fiber laser, which operating at 2.78 μm, stable Qswitched pulse was obtained and the repetition rate was from 78.79 kHz to 162.32 kHz. The recorded maximum average output of 865 mW was achieved.
