64-fs ultrashort pulse generation from a Kerr-lens mode-locked (Yb <sub>0.058</sub> Sc <sub>0.508</sub> Y <sub>0.434</sub> ) <sub>2</sub> O <sub>3</sub> ceramic laser
We have successfully used a mixed sesquioxide ceramic (Yb<sub>0.058</sub>Sc<sub>0.508</sub>Y<sub>0.434</sub>)<sub>2</sub>O<sub>3</sub> (Yb:YScO<sub>3</sub>) as a gain medium for femtosecond laser generation via Kerr-lens mode-locked laser technology. A high-brightness diode laser has been used for pumping the ceramic sample, and a stable pulsed laser with a time duration of 64 fs and an average output power exceeding 100 mW at a peak wavelength of 1046 nm has been achieved. This is the first, to the best of our knowledge, report of femtosecond laser operation using mixed sesquioxide ceramic as a gain medium, and the time-domain width of the obtained pulsed laser is also one of the shortest in Yb-doped ceramic material mode-locked lasers.
