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.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
