Femtosecond pulse generation from a semiconductor saturable absorber mirror mode-locked Yb:LuYAG mixed crystal laser

We report on a femtosecond semiconductor saturable absorber mirror (SESAM) mode-locked Yb:LuYAG laser. Pumped by a 976 nm single-mode fiber laser, a self-starting mode-locked Yb:LuYAG laser was demonstrated, delivering a 618-mW output power with 140-fs pulses and a 95.4-MHz repetition rate. The output spectrum is centered at 1053 nm with a spectral width of 10.4 nm. To the best of our knowledge, this is the shortest pulse ever generated from a mode-locked Yb:LuYAG laser.
